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): Add bus pass-aware discovery of platform devices (PMU,
NVRAM, ChipCommon, etc).

This extends the existing handling of NVRAM core discovery to support
locating additional devices that may be attached either directly as real
cores, or indirectly via ChipCommon (e.g. bhnd_pmu).

When attached as a SoC root bus (as opposed to a bridged WiFi device),
the platform devices may not be attached until later bus passes,
necessitating delayed discovery/initialization.

[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.

* 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.

This is necessary to support SROM/OTP child devices that live directly

of the standard behavior of delegating access to the bridged SoC address
space.

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!

newbus: Move from bus_child_{pnpinfo,location}_src to bus_child_{pnpinfo,location} with sbuf

Now that the upper layers all go through a layer to tie into these
information functions that translates an sbuf into char * and len. The
current interface suffers issues of what to do in cases of truncation,
etc. Instead, migrate all these functions to using struct sbuf and these
issues go away. The caller is also in charge of any memory allocation
and/or expansion that's needed during this process.

Create a bus_generic_child_{pnpinfo,location} and make it default. It
just returns success. This is for those busses that have no information
for these items. Migrate the now-empty routines to using this as
appropriate.

Document these new interfaces with man pages, and oversight from before.
