Use snd_soc_component_update_bits() function to replace the regmap_update_bits(), for snd_soc_component_update_bits() has the capability of return check status. Also enable pm runtime before calling the function snd_soc_component_update_bits() to make the regmap cache data align with the value in hardware.
