ASoC: codecs: cs35l32: Propagate regcache_sync() errors

Browse Source 
regcache_sync() can fail while replaying cached register state during
runtime resume. cs35l32_runtime_resume() currently ignores that failure.

Propagate the error, restore cache-only/dirty state, and unwind the
reset and supply state acquired by runtime resume.
