ath9k: Add definitions and structures to support WoW
*add structures, macros and variables for WoW, so that the driver can make use of it. *maintain a list for user enabled patterns and masks *track pattern slots for the hardware limitation on the maximum number of patterns that can be stored. *track interrupts enabled before WoW suspend, so that can be reconfigured after resume *have macros to parse user defined wow configurations to hardware code Cc: Senthil Balasubramanian <senthilb@qca.qualcomm.com> Cc: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Cc: vadivel@qca.qualcomm.com Signed-off-by: Luis R.
