ath9k: Fix issues with WoW enable
This patch addresses several issues with the
ath9k_hw_wow_enable() routine:
* The usage of set/clr variables is removed. Writing
the required values to registers is cleaner.
* The shift value of 28 for the contention window field
in AR_WOW_PATTERN is incorrect, change it to 27.
* Disabling Keep Alive needs to be done based on the
LINK_CHANGE option. This is done unconditionally now,
fix this.
* The workaround for the D1/D3 issue is required only
for AR9462.
* The bitfield for enabling pattern matching for packets
less than 256 bytes has expanded for new chips, handle
this accordingly.
* General cleanup.
