[ath_hal] Allow the BT antenna diversity option to be enabled for QCA9565.

Obtained from: Linux ath9k

Add TXOP enforce support to the AR9300 HAL.

This is required for (more) correct TDMA support. Without it, the
code tries to calculate the required guard interval based on the
current rate, and since this is an 11n NIC and people try using
11n, it calls ath_hal_computetxtime() on an 11n rate which then
panics.

This doesn't fix TDMA slave mode on AR9300 - it just makes it
have one less bug.

Expose the ANI state / statistics using the public ANI function, rather than
the ar9300_* definitions.

.. which of course don't match, and athstats was reading garbage ANI
data.

Add initial support to the AR9300 HAL to support FreeBSD's intmit API.

I don't like having it in this function; I may migrate it to ar9300_freebsd.c
at some point to keep the HAL code pollution down.

This allows ANI to be disabled via a sysctl.

Tested:

* AR9331, STA/TDMA modes

Update the AR9300 HAL to the latest public available HAL from QCA.

I've been sitting on this for a year or so now; I've finally
tested it on enough devices to be reasonably sure it won't
cause too much drama. But, if you see issues, please email me.

Tested (all STA mode):

PCIe:

* AR9380
* AR9390
* AR9580
* AR9462
* AR9485

SoC:

* QCA9550
* AR9331
* AR9342

Disable TXCONT, it's not here in FreeBSD.

There's no HAL_EEPROM in FreeBSD - use ar9300_eeprom_t instead.

Bring over my FreeBSD modifications for the AR9300 HAL to make it
work in FreeBSD.

This is still heavily a work in progress but I'd rather it start
shipping in -HEAD sooner rather than later.

This doesn't (yet) link it into the build system either for a static
kernel or as a module; that will come later (after many, many make universe
tests.)

Copy the vendor branch ar9300 code from qcamain_open_hal into this
directory.

Only copy the ar9300 HAL, we don't want to grab everything.

Initial import of the QCA qcamain_open_hal repository.
