ALSA: hda: cs35l41: Ensure we correctly re-sync regmap before system suspending.

Browse source

In order to properly system suspend, it is necessary to unload the firmware
and ensure the chip is ready for shutdown (if necessary). If the system
is currently in runtime suspend, it is necessary to wake up the device,
and then make it ready. Currently, the wake does not correctly resync
the device, which may mean it cannot suspend correctly. Fix this by
performaing a resync.
