bhnd(4): Add devinfo allocation and child addition methods, modeled on
pci_if.

This allows bhnd(4) to manage per-device state (such as per-core
pmu/clock refcounting) on behalf of subclass driver instances.

Approved by: re (gjb), adrian (mentor)
Differential Revision: https://reviews.freebsd.org/D6959

bhnd(4): Perform explicit chipc child enumeration.

Replaces use of DEVICE_IDENTIFY with explicit enumeration of chipc
child devices using the chipc capability structure.

This is a precursor to PMU support, which requires more complex resource
assignment handling than achievable with the static device name-based
hints table.

Fix several MIPS/BCM-blocking bugs in bhnd(4) chipc

- Correct IRQ lines for UART (to fix IRQ lookup in future)
- Check device unit in resource assignment during chipc_add_child
- If chipc hint->size is RM_MAX_END, resource end should be same as window end
- Clear reference from resource list entry to resource in case of resource release
- Add CHIPC_GET_CAPS implementation
- Correct chipc flash constants (to be unshifted)
- Default implementation of get_attach_type should iterate over device tree
- Add default implementation for BHND_CHIPC_GET_CAPS usable by chipc grandchildren

[bhnd] Add support for querying the attachment type of the bhnd bus.

This adds a BHND_BUS_GET_ATTACH_TYPE(); the primary use-case is to let
chipc make a coarse-grained determination as to whether UART, SPI, etc
drivers ought to be attached, and on fullmac devices, whether a real
CPU driver ought to be skipped for the ARM core, etc.

Tested:

* BCM4331 (BHND)
* BCM4312 (SIBA)

[bhnd] Add remaining bus_(read|write|set)_(1|2|4) APIs

This adds bhnd-compatible implementations of bus_(read|write|set)_(1|2|4) APIs,
and upgrades the SPROM parsing code to use bhnd_bus_read_region_stream_2().

This a precursor to bridge support for resource adjustment and the new
ChipCommon bus support.

Tested:

* Tested against BCM4331
* Kernel build verified via tinderbox.

[bhnd] Centralize fetching of board information

Centralizes fetching of board information (vendor, type, revision, etc),
and adds support for matching quirks against board identification info.

* Adds a BHND_BUS_READ_BOARD_INFO(), allowing bhnd bus/bus parent(s) to
handle implementation-specific fetching of board info.
* Integrates board type constants from the latest Broadcom ISC-licensed
bcmdevs.h included in dd-wrt's Broadcom driver source drops.
* Adds support for matching on chip/board quirks to bhnd_device_quirks()/
bhnd_chip_quirks().
* Use the new board/chip quirk matching to match Apple devices that failed
to set BFL2_PCIEWAR_OVR in SROM.

[bhnd] Initial bhnd(4) SPROM/NVRAM support.

This adds support for the NVRAM handling and the basic SPROM
hardware used on siba(4) and bcma(4) devices, including:

* SPROM directly attached to the PCI core, accessible via PCI configuration
space.
* SPROM attached to later ChipCommon cores.
* SPROM variables vended from the parent SoC bus (e.g. via a directly-attached
flash device).

Additional improvements to the NVRAM/SPROM interface will
be required, but this changeset stands alone as working
checkpoint.

[bhnd] Replace is_hostb_device() with a more general find_hostb_device()

This allows bus children to query for the host bridge device, rather
than having to iterate over all attached devices.

[bhnd] Clean up bhnd resource handling and inherited bus methods

To facilitate use by SoC implementors working with bhnd-inheriting fdt/nexus
drivers:

* Splits bhnd_bus method implementations into generic bus implementations
(bhnd_bus_generic) and generic bhnd(4) driver implementations (bhnd_generic)
* Simplifies bhnd resource handling, allowing bhnd bus implementations to
support bhnd resource activation by implementing the standard BUS_*
resource APIs and BHND_BUS_ACTIVATE_RESOURCE().

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!
