[PATCH] ASoC: codecs: wsa881x: Propagate regcache_sync() errors

[Pengpeng Hou]

wsa881x_runtime_resume() powers the device up, waits for SoundWire
initialization, leaves cache-only mode, and replays cached register
state. It currently ignores regcache_sync() failures and returns
success.

Propagate sync failures, restore cache-only/dirty state, and undo the
shutdown GPIO state acquired by resume.
