ASoC: codecs: wm5100: Propagate regcache_sync() errors

Browse Source 
regcache_sync() can fail while replaying cached register state during
runtime resume. wm5100_runtime_resume() currently ignores that failure.

Propagate the error, restore cache-only/dirty state, and unwind the LDO
and core supplies acquired by runtime resume.
