ath9k_hw: Do full chip reset on 11A channels for AR9003

Browse Source 
AR9003 seems to have issues sometimes with fast channel change
in 5GHz and this case is handled specifically for AR9280 by doing
a full reset. Let's do a full reset for 5GHz channles of AR9380
& for all channels of AR9280 pci chips.
