ASoC: cs35l41: Add common cs35l41 enter hibernate function
Since the CS35L41 HDA driver also support hibernation, it
makes sense to move code from the ASoC driver to enter
hibernation into common code.
Since HDA must support laptops which do not support hibernation
due to lack of external boost GPIO it is necessary to
ensure the function returns an error when an unsupported
boost type is in use.
