soc: swr-mstr-ctrl: porting fix from wcd controller to mstr controller

Browse source 
When temperature on a single wsa881x device is being read,
then soundwire master wakes up both wsa881x devices but
regcache_sync is happening only for one wsa881x device on
which the temperature is being read. This results in
audio playback mute after temperature read. Fix the
regcache sync during temperature read and playback usecase.
