[PATCH 2/7] ath9k: Set keep awake timer

[Sujith Manoharan <sujith@msujith.org>]

From: Sujith Manoharan <c_manoha@qca.qualcomm.com>

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.
