ALSA: hda: cs35l41: Don't return -EINVAL from system suspend/resume

Browse Source 
The recent commit to support the system suspend for CS35L41 caused a
regression on the models with CS35L41_EXT_BOOST_NO_VSPK_SWITC boost
type, as the suspend/resume callbacks just return -EINVAL.  This is
eventually handled as a fatal error and blocks the whole system
suspend/resume.

For avoiding the problem, this patch corrects the return code from
cs35l41_system_suspend() and _resume() to 0, and replace dev_err()
with dev_err_once() for stop spamming too much.
