[ath_hal] implement shared PA handling checks, based on ath9k.
These are apparently conditional on there being a shared PA/LNA, which at least on AR9462/QCA9535 devices I have isn't a thing. I'm .. not yet sure which devices it /is/ a thing, so I'll come back to that. Tested: * QCA9565 STA + bluetooth Obtained from: Linux ath9k
