[ath_hal] add QCA9565 bluteooth antenna control.

Browse Source 
This configures the LNA antenna diversity control, which should be on
if wlan owns the LNA for bluetooth coexistence.  Otherwise, make sure
it's off.

I think this is eventually intended to allow 1-antenna bluetooth +
wifi setups for QCA9565, but I'm not sure where that's actually configured
in ath9k.
