ASoC: soc-io: Fix snd_soc_component_update_bits_legacy
has been applied to the asoc tree at

After the codec to component conversion codecs with custom read/write function will no longer able to use update_bits as their io callbacks are registered at component->driver level and not in component level.
To not complicate the code further, lets just use the snd_soc_component_read/snd_soc_component_write function and let them sort out the correct io function to call.
