asoc: codecs: Update muxsel registers only when clock counts are not stale

Selaa lähdekoodia 
During SSR/PDR use cases, core clock count in different
macros becomes stale and muxsel registers are accessed
leading to NOC errors. Update muxsel registers only after
clock counts are reset after SSR/PDR recovery.
