[ath_hal] add a _S so FSP (frame scheduling policy) can be set/read via SM/MS macros.

[ath_hal] add QCA9565 and MCI related registers.

This is required for upcoming MCI fixes.

Add initial support for the QCA953x SoC (honeybee) wifi.

This is a 2x2 2GHz 802.11n part. It works enough at the moment to
bring up, scan and associate. I haven't started using this as
a day to day AP.

The specifics:

* add honeybee initvals
* add in changes; a mix from the QCA HAL and ath9k;
* fix a bug in AR_SREV_AR9580_10_OR_LATER(), which is only used
for one capability check and we don't even implement it - so it's
a big no-op.

Shady things:

* ath9k has the "platform data" define the 25/40MHz clock.
This HAL .. doesn't. Honeybee gets hard-coded to 25MHz which
it likely shouldn't be. I'll have to go and identify/fix those.

Tested:

* Qualcomm Atheros AP143 reference design board.
