ASoC: max98090: sync regcache on entering STANDBY

Browse source 
commit c42c8922c4 upstream.

Sync regcache when entering STANDBY from OFF.  ON isn't entered with
OFF as the current state, so the registers were not being re-synced
after suspend/resume.

The 98088 and 98095 already call regcache_sync from STANDBY.
