7239f9f75b Introduce the FRAC_5G EEPROM parameter.
This seems to indicate whether to program the NIC for fractional 5ghz
mode (ie, 5mhz spaced channels, rather than 10 or 20mhz spacing) or not.
The default (0) seems to mean "only program fractional mode if needed".
A different value (eg 1) seems to always enable fractional 5ghz mode
regardless of the frequency.

acc8122719 Fix the Merlin 5ghz fast-clock EEPROM fetch to return the correct value.
The eeprom Get method should return HAL_OK if fastclock is enabled in the
EEPROM. It was returning the opposite of what it should have.

92ffeb633d Fix the eeprom set API method to return HAL_STATUS.
The code assumed it could return HAL_OK, HAL_EINVAL and other
HAL_STATUS types; so it shouldn't be declared as returning HAL_BOOL.

9f25ad52ce 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.

74e3a02137 The xpaBiasLvlFreq[] fields in the modal header also need swapping
when the EEPROM contents are byte-swapped.

c50678682f Introduce the Merlin PWDCLKIND workaround.
This is something bus clock related from what I can gather. It is needed for
the AR9220 based Ubiquiti SR71-12 and SR71-15 Mini-PCI NICs.

(Note: those NICs don't work right now because of earlier changes to handle
power table offset correctly. That'll be resolved in a follow-up commit.)

8823714276 Add an EEPROM op that extracts out the power table offset.
It defaults to -5 dBm for eeproms earlier than v21.

This apparently only applies to Merlin (AR9280) or later,
earlier 11n chipsets have a power table offset of 0.
All the code in ath9k which checks the power table offset
and takes it into account first ensures the chip is
Merlin or later.

a5314ffdf0 Modify the v14/v4k eeprom diag interface to return the whole eeprom.
The v1 and v3 interfaces returned the whole EEPROM but the v14/v4k
interfaces just returned the base header. There's extra information
outside of that which would also be nice to get access to.

c485136b7f Port over another EEPROM option from ath9k - AR_EEP_DAC_HPWR_5G
This will be used by the temperature compensation calibration code
which will shortly make an appearance.
