ath9k: Add WoW related mac80211 callbacks
add suspend/resume/set_wakeup callbacks to the driver
*suspend
- bail out only if all the conditions for configuring WoW.
is fine, currently multivif case is not handled
- check for associated state.
- map wow triggers from user space data.
- add deauth/disassoc pattern and user defined pattern,
for the later a list is maintained.
- store the interrupt mask before suspend, enabled beacon
miss interrupt for WoW.
- configure WoW in the hardware by calling ath9k_hw_wow_enable.
*resume
- restore the interrupts based on the interrupt mask
stored before suspend.
- call ath9k_hw_wow_wakeup to configure/restore the hardware.
- after wow wakeup clear away WoW events and query the
WoW wakeup reason from the status register
*set_wakeup
- to call 'device_set_wakeup_enable' from cfg80211/mac80211
when wow is configured and as per Rafael/Johannnes the
right way to do so rather in the driver suspend/resume
call back
