bhnd(4): Add a vendor parameter to BHND_DEVICE(), replacing vendor-specific
BHND_*_DEVICE macros.

Approved by: adrian (mentor)
Differential Revision: https://reviews.freebsd.org/D6736

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] 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.

[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] Finish bhnd(4) PCI/PCIe-G1 hostb support.

Now that we've got access to SPROM and can access board identification,
this implements all known remaining hardware work-arounds for the bhnd(4)
PCI and PCIe-G1 cores operating endpoint mode.

Additionally, this adds an initial set of skeleton PCIe-G2 hostb and pcib
drivers, required by fullmac and newer softmac devices.

[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] Add logging macros to BHND.

There are 5 logging levels:

* ERROR
* WARN
* INFO
* DEBUG
* TRACE

There are 2 logging context:

* with
* without device

DEBUG and TRACE records are printed only if bootverbose.
Logging records are printed with source code line information if acceptable
logging level is DEBUG or TRACE.

[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.

Replace all resource occurrences of '0UL/~0UL' with '0/~0'.

Summary:
The idea behind this is '~0ul' is well-defined, and casting to uintmax_t, on a
32-bit platform, will leave the upper 32 bits as 0. The maximum range of a
resource is 0xFFF.... (all bits of the full type set). By dropping the 'ul'
suffix, C type promotion rules apply, and the sign extension of ~0 on 32 bit
platforms gets it to a type-independent 'unsigned max'.

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!
