ath9k: enable the baseband watchdog events for AR9003
This enables the baseband watchdog events for the AR9003
family on ath9k. Upon an a baseband watchdog interrupt we reset
the hardware, this should address corner case conditions where
normal operation can stall. Enable ATH_DBG_RESET to be able
to review details of the bb watchdog interrupt once it happens.
If you're curious how often this happens just grep the debugfs
interrupt file.
