bhndb(4): Implement bridge support for the BCM4312 and other PCI_V0 chipsets.

Very early (PCI_V0) Broadcom PCI Wi-Fi chipsets have a few quirks when
compared to later PCI(e) core revisions:

- The standard static BAR0 mapping of the PCI core registers is discontiguous,
with siba's cfg0 register block mapped distinctly from the other core
registers.
- No dedicated ChipCommon register mapping is provided; instead, the
single configurable register window must be used to access both
ChipCommon and D11 core registers. The D11 core's operational semantics
guarantee the safety of -- after disabling interrupts -- borrowing
the single dynamic register window to perform the few ChipCommon
operations required by a driver.

To support these early PCI devices:

- Allow defining multiple discontiguous BHNDB_REGWIN_T_CORE register
windows that map a single port/region, and producing bridged resource
allocations backed by those discontiguous windows.
- Support stealing existing register window allocations to fulfill indirect
bhnd(4) bus I/O requests within address ranges tagged with
BHNDB_ALLOC_FULFILL_ON_OVERCOMMIT.
- Fix an inverted test of bhndb_is_pcie_attached() that disabled
PCI-only clock bring-up required by these devices.

bhnd(4): Add support for querying DMA address translation parameters

BHND Wi-Fi chipsets and SoCs share a common DMA engine, operating within
backplane address space. To support host DMA on Wi-Fi chipsets, the bridge
core maps host address space onto the backplane; any host addresses must
be translated to their corresponding backplane address.


- Defines a new bhnd_get_dma_translation(9) API to support querying DMA
address translation parameters from the bhnd(4) bus.
- Extends bhndb(4) to provide DMA translation descriptors from a DMA
address translation table defined in the host bridge-specific
bhndb_hwcfg.
- Defines bhndb(4) DMA address translation tables for all supported host
bridge cores.
- Extends mips/broadcom's bhnd_nexus driver to return an identity (no-op)
DMA translation descriptor; no translation is required when addressing
the SoC backplane.

bhnd(4): implement MIPS and PCI(e) interrupt support

On BHND MIPS SoCs, this replaces the use of hard-coded MIPS IRQ#s in the
common bhnd(4) core drivers; we now register an INTRNG child PIC that
handles routing of backplane interrupt vectors via the MIPS core.

On BHND PCI devices, backplane interrupt vectors are now routed to the
PCI/PCIe host bridge core when bus_setup_intr() is called, where they are
dispatched by the PCI core via a host interrupt (e.g. INTx/MSI).

The bhndb(4) bridge driver tracks registered interrupt handlers for the
bridged bhnd(4) devices and manages backplane interrupt routing, while
delegating actual bus interrupt setup/teardown to the parent bus on behalf
of the bridged cores.

bhnd: Add support for supplying bus I/O callbacks when initializing an EROM
parser.

This allows us to use the EROM parser API in cases where the standard bus
space I/O APIs are unsuitable. In particular, this will allow us to parse
the device enumeration table directly from bhndb(4) drivers, prior to
full attach and configuration of the bridge.

Migrate bhndb(4) to the new bhnd_erom API.

Adds support for probing and initializing bhndb(4) bridge state using
the bhnd_erom API, ensuring that full bridge configuration is available
*prior* to actually attaching and enumerating the bhnd(4) child device,
allowing us to safely allocate bus-level agent/device resources during
bhnd(4) bus enumeration.

- Add a bhnd_erom_probe() method usable by bhndb(4). This is an analogue
to the existing bhnd_erom_probe_static() method, and allows the bhndb
bridge to discover the best available erom parser class prior to newbus
probing of its children.
- Add support for supplying identification hints when probing erom
devices. This is required on early EXTIF-only chipsets, where chip
identification registers are not available.
- Migrate bhndb over to the new bhnd_erom API, using bhnd_core_info
records rather than bridged bhnd(4) device_t references to determine
the bridged chipsets' capability/bridge configuration.
- The bhndb parent (e.g. if_bwn) is now required to supply a hardware
priority table to the bridge. The default table is currently sufficient
for our supported devices.
- Drop the two-pass attach approach we used for compatibility with bhndb(4) in
the bhnd(4) bus drivers, and instead perform bus enumeration immediately,
and allocate bridged per-child bus-level resources during that enumeration.

[bhnd] Normalize bhnd(4) device matching API

This unifies handling of core, chip, and board-level device
matching, and adds support for matching device drivers
against the bus attach type (e.g. SoC vs WiFi adapter).

Core-level quirks on Broadcom's chipsets generally are specific
to some combination of chip model, core revision, chip
package (e.g. 12x9 SMT package), SROM revision, etc.

Unifying the match APIs for all three attribute types (core, chip,
board/srom) allows defining a single device quirk table that
matches across all of those attributes.

[bwn] [bhnd] initial support for using bhnd for if_bwn devices.

This is an initial work in progress to use the replacement bhnd
bus code for devices which support it.

* Add manpage updates for bhnd, bhndb, siba
* Add kernel options for bhnd, bhndbus, etc
* Add initial support in if_bwn_pci / if_bwn_mac for using bhnd
as the bus transport for suppoted NICs
* if_bwn_pci will eventually be the PCI bus glue to interface to bwn,
which will use the right backend bus to attach to, versus direct
nexus/bhnd attachments (as found in embedded broadcom devices.)

The PCI glue defaults to probing at a lower level than the bwn glue,
so bwn should still attach as per normal without a boot time tunable set.

It's also not fully fleshed out - the bwn probe/attach code needs to be
broken out into platform and bus specific things (just like ath, ath_pci,
ath_ahb) before we can shift the driver over to using this.

Tested:

* BCM4311, STA mode
* BCM4312, STA mode

[bhnd] Add support for specifying the address space used by bhndb children

This adds support for specifying the address space used by a bridge child;
this will either be the bridged SoC address space, or the host address space
required by children that map non SoC-address ranges from the PCI BAR.

This is necessary to support SROM/OTP child devices that live directly
beneath the bhndb device and require access to host resources, instead
of the standard behavior of delegating access to the bridged SoC address
space.
