ath9k: make rfkill configurable

When the platform doesn't have rfkill support, i.e. nothing
is connected to the rfkill GPIO, there's little value in
polling the GPIO. Add a Kconfig option to allow disabling
the polling in ath9k.

Say Y to have ath9k poll the RF-Kill GPIO every couple of
seconds. Turn off to save power, but enable it if you have
a platform that can toggle the RF-Kill GPIO.
