[PATCH v5 07/16] ALSA: hda: cs35l41: Put the device into safe mode for external boost

To facilitate the configuration of external boost devices, put all
devices, with or without VSPK switch, into safe mode from the start.
That allows the following parts of the driver to handle all external
boost devices in the same way.
