ASoC: cs35l45: Hibernate wm_adsp on runtime suspend
When the CS35L45 driver suspends, it is put into hibernation, and
the regmap goes into cache_only, but the firmware is still running, and
wm_adsp is not stopped. If userspace attempts to read a firmware
control, it will perform a regmap_raw_read() and this will produce an
error in the kernel log. To prevent spurious errors, put the DSP into
hibernation which prevents access to the hardware for the ALSA
controls.
