WLAN RFA is present on another co-processor subsystem.
Any error fatal in co-processor subsystem will result in
WLAN reset.
In order to make sure that rf clock/rails are up before
accessing WLAN hardware, ICNSS platform driver needs to
register with co-processor SSR notification and wait for
POWER_UP event before starting QMI handshake.
