From: Sujith Manoharan <c_manoha@xxxxxxxxxxxxxxxx>
* ath9k_mci_update_rssi() is required only for
cards that use MCI scheme. Make sure that it
is not called for 3-wire cards.
* Call ath9k_ps_wakeup() early since register
accesses are made in ath9k_mci_update_rssi().
* Fix usage of btcoex_lock to handle no_stomp_timer.
