The power save state of MCI has to be disabled
when enabling WoW sleep, check this properly.
ar9003_mci_state() doesn't handle MCI_STATE_GET_WLAN_PS_STATE
right now, but this will be done later when proper
support for MCI/PS is added.

When MCI is enabled and WoW sleep is enabled,
make sure that the RTC keep awake timer is set
with the required value. This is also required
when the AR_WA is programmed.

Along with AR9462, AR9565 also has an extra field
in the TX descriptor which needs to be zeroed out
for the keep alive frame. This makes the earlier
REG_WRITE redundant, so it can be removed.

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.

Newer chips like WB222, WB335 support more than
8 user-configurable patterns. This patch adds
support for it by setting up the correct HW
registers.

Since the maximum number of configurable patterns
is chip-specific, use the HW capability instead
of a fixed value for checking if a free pattern
slot is available.

The HW routines to set various WoW registers are present
in wow.c. For some reason, it has been compiled as part
of the main ath9k.ko module all this time, when it should
really be part of ath9k_hw.ko. This patch renames the file to
ar9003_wow.ko and adds it to ath9k_hw.ko.
