bhnd(4): Correct some typos in source code comments

bhnd: clean up empty lines in .c and .h files

bhnd(4): include a subset of the ChipCommon capability flags in bhnd_chipid;
this provides early access to device capability flags required by bhnd(4)
bus and bhndb(4) bridge drivers.

bhnd(4)/bwn(4): Fix a number of small issues reported by Coverity.

the dynamic window count is 0.

- Fix incorrect bhnd_pmu(4) UPTME_MASK and PLL0_PC2_WILD_INT_MASK
constants.

- Variable definitions referenced by our generated SPROM layouts will never
be NULL, but add explicit asserts to make that clear.

- Add missing variable initialization in bhnd_nvram_sprom_ident().

- Fix leak of driver array in bhnd_erom_probe_driver_classes().

- Fix zero-length memset() in bhndb_pci_eio_init().

- Fix an off-by-one error and potential invalid OOBSEL bit shift operation
in bcma_dinfo_init_intrs().

- Remove dead code in siba_suspend_hw().

- Fix duplicate call to bhnd_pmu_enable_regulator() in both the enable and
disable code paths of bhnd_compat_cc_pmu_set_ldoparef().

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.

Implement a generic bhnd(4) device enumeration table API.

This defines a new bhnd_erom_if API, providing a common interface to device
enumeration on siba(4) and bcma(4) devices, for use both in the bhndb bridge
and SoC early boot contexts, and migrates mips/broadcom over to the new API.

This also replaces the previous adhoc device enumeration support implemented
for mips/broadcom.

Migration of bhndb to the new API will be implemented in a follow-up commit.


- Defined new bhnd_erom_if interface for bhnd(4) device enumeration, along
with bcma(4) and siba(4)-specific implementations.
- Fixed a minor bug in bhndb that logged an error when we attempted to map the
full siba(4) bus space (18000000-17FFFFFF) in the siba EROM parser.
- Reverted use of the resource's start address as the ChipCommon enum_addr in
bhnd_read_chipid(). When called from bhndb, this address is found within the
host address space, resulting in an invalid bridged enum_addr.
- Added support for falling back on standard bus_activate_resource() in
bhnd_bus_generic_activate_resource(), enabling allocation of the bhnd_erom's
bhnd_resource directly from a nexus-attached bhnd(4) device.
- Removed BHND_BUS_GET_CORE_TABLE(); it has been replaced by the erom API.
- Added support for statically initializing bhnd_erom instances, for use prior
to malloc availability. The statically allocated buffer size is verified both
at runtime, and via a compile-time assertion (see BHND_EROM_STATIC_BYTES).
- bhnd_erom classes are registered within a module via a linker set, allowing
mips/broadcom to probe available EROM parser instances without creating a
strong reference to bcma/siba-specific symbols.
- Migrated mips/broadcom to bhnd_erom_if, replacing the previous MIPS-specific
device enumeration implementation.
