[ath] [ath_hal] Propagate the HAL_RESET_TYPE through to the chip reset; set it during ath_reset()

Although I added the reset type field to ath_hal_reset() years ago,
I never finished adding it both throughout the HALs and in if_ath.c.

This will eventually deprecate the ath_hal force_full_reset option
because it can be requested at the driver layer.

So:

* Teach ar5416ChipReset() and ar9300_chip_reset() about the HAL type
* Use it in ar5416Reset() and ar9300_reset() when doing a full chip reset
* Extend ath_reset() to include the HAL_RESET_TYPE parameter added in the above functions
* Use HAL_RESET_NORMAL in most calls to ath_reset()
* .. but use HAL_RESET_BBPANIC for the BB panics, and HAL_RESET_FORCE_COLD during fatal, beacon miss and other hardware related hangs.

This should be a glorified no-op outside of actual hardware issues.
I've tested things with ath_hal force_full_reset set to 1 for years now,
so I know that feature and a full reset works (albeit much slower than
a warm reset!) and it does unwedge hardware.

The eventual aim is to use this for all the places where the driver
detects a potential hang as well as if long calibration - ie, noise floor
calibration - fails to complete. That's one of the big hardware related
things that causes station mode operation to hang without easy recovery.

Add initial support for the AR9485 CUS198 / CUS230 variants.

These variants have a few differences from the default AR9485 NIC,
namely:

* a non-default antenna switch config;
* slightly different RX gain table setup;
* an external XLNA hooked up to a GPIO pin;
* (and not yet done) RSSI threshold differences when
doing slow diversity.

To make this possible:

* Add the PCI device list from Linux ath9k, complete with vendor and
sub-vendor IDs for various things to be enabled;
* .. and until FreeBSD learns about a PCI device list like this,
write a search function inspired by the USB device enumeration code;
* add HAL_OPS_CONFIG to the HAL attach methods; the HAL can use this
to initialise its local driver parameters upon attach;
* copy these parameters over in the AR9300 HAL;
* don't default to override the antenna switch - only do it for
the chips that require it;
* I brought over ar9300_attenuation_apply() from ath9k which is cleaner
and easier to read for this particular NIC.

This is a work in progress. I'm worried that there's some post-AR9380
NIC out there which doesn't work without the antenna override set as
I currently haven't implemented bluetooth coexistence for the AR9380
and later HAL. But I'd rather have this code in the tree and fix it
up before 11.0-RELEASE happens versus having a set of newer NICs
in laptops be effectively RX deaf.

Tested:

* AR9380 (STA)
* AR9485 CUS198 (STA)

Bring over the basic spectral scan framework code from Qualcomm Atheros.

This includes the HAL routines to setup, enable/activate/disable spectral
scan and configure the relevant registers.

This still requires driver interaction to enable spectral scan reporting.
Specifically:

* call ah_spectralConfigure() to configure and enable spectral scan;
* .. there's currently no way to disable spectral scan... that will have
to follow.
* call ah_spectralStart() to force start a spectral report;
* call ah_spectralStop() to force stop an active spectral report.

The spectral scan results appear as PHY errors (type 0x5 on the AR9280,
same as radar) but with the spectral scan bit set (0x10 in the last byte
of the frame) identifying it as a spectral report rather than a radar
FFT report.

Caveats:

* It's likely quite difficult to run spectral _and_ radar at the same
time. Enabling spectral scan disables the radar thresholds but
leaves radar enabled. Thus, the driver (for now) needs to ensure
that only one or the other is enabled.

* .. it needs testing on HT40 mode.

Tested:

* AR9280 in STA mode, HT/20 only

TODO:

* Test on AR9285, AR9287;
* Test in both HT20 and HT40 modes;
* .. all the driver glue.

HAL updates!

* Add some more ANI spur immunity levels.
* For AR5111 radios attached to an AR5212, limit the 5GHz channels
that are available. A later revision of the AR5111 supports the 4.9GHz
PSB channels but right now there's no check in place for the radio
revision.

If someone wants PSB support on AR5212+AR5111 radios then please let
me know and I'll add the relevant version check.
