Add device identification and probe/attach support for the QCA9565.

The QCA9565 is a 1x1 2.4GHz 11n chip with integrated on-chip bluetooth.
The AR9300 HAL already has support for this chip; it just wasn't
included in the probe/attach path.

Tested:

* This commit brought to you over a QCA9565 wifi connection from
FreeBSD.
* .. ie, basic STA, pings, no iperf or antenna diversity checking just yet.

Add the emulation PCI device id - these days, 0xabcd shows up all over
the internet as "AR9380 and later which didn't get its PCI ID written
in at power-on", so it's hardly an unknown constant.

Correct device id comments.

Merlin -> Kiwi

AR9287 prep work:

* Add PCI/PCIE devids
* Add AR9287/Kiwi version check macros
* AR_SREV_9287 -> AR_SREV_KIWI

Introduce AR9130 (HOWL) WMAC support to the FreeBSD HAL.

The AR9130 is an AR9160/AR5416 family WMAC which is glued directly
to the AR913x SoC peripheral bus (APB) rather than via a PCI/PCIe
bridge.

The specifics:

* A new build option is required to use the AR9130 - AH_SUPPORT_AR9130.
This is needed due to the different location the RTC registers live
with this chip; hopefully this will be undone in the future.
This does currently mean that enabling this option will break non-AR9130
builds, so don't enable it unless you're specifically building an image
for the AR913x SoC.

* Add the new probe, attach, EEPROM and PLL methods specific to Howl.

* Add a work-around to ah_eeprom_v14.c which disables some of the checks
for endian-ness and magic in the EEPROM image if an eepromdata block
is provided. This'll be fixed at a later stage by porting the ath9k
probe code and making sure it doesn't break in other setups (which
my previous attempt at this did.)

* Sprinkle Howl modifications throughput the interrupt path - it doesn't
implement the SYNC interrupt registers, so ignore those.

* Sprinkle Howl chip powerup/down throughout the reset path; the RTC methods
were

* Sprinkle some other Howl workarounds in the reset path.

* Hard-code an alternative setup for the AR_CFG register for Howl, that
sets up things suitable for Big-Endian MIPS (which is the only platform
this chip is glued to.)

This has been tested on the AR913x based TP-Link WR-1043nd mode, in
legacy, HT/20 and HT/40 modes.

Caveats:

* 2ghz has only been tested. I've not seen any 5ghz radios glued to this
chipset so I can't test it.

* AR5416_INTERRUPT_MITIGATION is not supported on the AR9130. At least,
it isn't implemented in ath9k. Please don't enable this.

* This hasn't been tested in MBSS mode or in RX/TX block-aggregation mode.

Include the device ids for the AR2427.

This is apparently an AR9285 with the 802.11n specific bits disabled.

This code is completely untested; I'm doing this in response to users
who wish to test the functionality out. It's likely as buggy as the
AR9285 support is in FreeBSD at the moment.

Replace Id keyword with FreeBSD keyword and set the svn props correctly.
No functional change.

Update to later code from my repository:
o many bug fixes
o add new periodic calibration api
o break up 5416 periodic calibration code in preparation for 928x
o move get noise floor to rf backends
o 5416-specific ani (still disabled)
o modularize 5210 eeprom format a la other eeprom formats
o start cleaning up regdomain code
o prepare for proper 1/2 and 1/4 width channel support
o bring back 900MHz card support
o clean up 5212 rf version handling
o add 1/2 and 1/4 width channel support for 5212 parts
o split 5212 rfgain handling out
o improve ani debugging
o add AH_USE_INIPDGAIN compile option
o purge a bunch of dead 5212 state
o add 1/2 and 1/4 rate modes
o remove HAL_CAP_CHAN_HALFRATE and HAL_CAP_CHAN_QUARTERRATE; the
same info can now be deduced from the set of supported modes
