kernel: mac80211: enable the gpio controller for all ath9k devices

Browse Source 
This enables ath9k's built-in GPIO controller for all chip versions
(instead of an explicit whitelist). This also allows us to get rid of
some duplicate code between hw.c and gpio.c because hw.c already
determines the number of GPIOs.
