ASoC: codecs: tas2552: Propagate regcache_sync() errors

Browse Source 
regcache_sync() can fail while replaying cached register state after
runtime resume. tas2552_runtime_resume() currently ignores that failure
and returns success.

Propagate the error, restore cache-only/dirty state, and put the
amplifier back into shutdown on sync failure.
