ALSA: hda: cs35l56: Exit cache-only after cs35l56_wait_for_firmware_boot()
Adds calls to disable regmap cache-only after a successful return from
cs35l56_wait_for_firmware_boot().
This is to prepare for a change in the shared ASoC module that will
leave regmap in cache-only mode after cs35l56_system_reset(). This is
to prevent register accesses going to the hardware while it is
rebooting.
