ASoC: msm_sdw: Fix crash after SSR on speaker+BT ringtone 



Observe crash when trigger SSR while ringtone play on
speaker+BT usecase. Due to race condition, AHB timeout
happens as codec register accessed without clock enabled.
Clock enable flag is reset when SSR down event is received
to avoid any unclocked access.
