bhnd(4): Initial PMU/PWRCTL power and clock management support.


- Added bhnd_pmu driver implementations for PMU and PWRCTL chipsets,
derived from Broadcom's ISC-licensed HND code.
- Added bhnd bus-level support for routing per-core clock and resource
power requests to the PMU device.
- Lift ChipCommon support out into the bhnd module, dropping
bhnd_chipc.

bhnd(4): support IPX OTP NVRAM/SPROM data source

Add support for fetching SPROM data from OTP on chipsets with an
IPX OTP controller (including the BCM43225).

This integrates the NVRAM data source into the chipc_caps capability
structure, and adds a sprom_offset field that can be used with OTP
to locate the SPROM image data (found within the general use
region, H/W subregion).

This also removes one of two duplicate parse error messages reported by
both the bhnd_sprom driver and the underlying SPROM parsing API.

[bhnd] Implement pass-through resource management for ChipCommon.

This patchset adds support to bhnd_chipc for sharing SYS_RES_MEMORY
resources with its children, allowing us to hang devices off of
bhnd_chipc that rely on access to a subset of the device register space
that bhnd_chipc itself must also allocate.

We could avoid most of this heavy lifting if RF_SHAREABLE+SYS_RES_MEMORY
wasn't limited to use with allocations at the same size/offset.

As a work-around, I implemented something similar to vga_pci.c, which
implements similar reference counting of of PCI BAR resources for its
children.

With these changes, chipc will use reference counting of SYS_RES_MEMORY
allocation/activation requests, to decide when to allocate/activate/
deactivate/release resources from the parent bhnd(4) bus.

The requesting child device is allocated a new resource from chipc's
rman, pointing to (possibly a subregion of) the refcounted bhnd resources
allocated by chipc.

Other resource types are just passed directly to the parent bhnd bus;
RF_SHAREABLE works just fine with IRQs.

I also lifted the SPROM device code out into a common driver, since this
now allows me to hang simple subclasses off of a common driver off of both
bhndb_pci and bhnd_chipc.

Tested:

* (landonf) Tested against BCM4331 and BCM4312, confirmed that SPROM still
attaches and can be queried.

Bring over the initial rewrite of the broadcom bus support found in their
SoCs and various chips (including, famously, their wifi chips.)

This is "just" (all 20,000 lines of it) code to enumerate the various
versions of busses inside these devices, including the PCI bridge and
the direct SIBA bridge found in MIPS chips.

It also includes shared code for some bus operations (suspend, resume, etc);
EEPROM/SROM/etc parsing and other things that are shared between chips.

Eventually this'll replace the code that bwi/bwn uses for the internal
bus, as well as some apparently upcoming mips74k broadcom SoC support
which uses bwn!

Thanks to Landon Fuller <landonf@landonf.org> for all this work!
