ASoC: cs4270: add Master Playback Switch

Browse source

This adds a new control named 'Master Playback Switch' for cs4270
codecs. It is implemented using the new SOC_DOUBLE_EXT macro to catch
the put function and store the information about manually set mute
controls from userspace. When a manual mute is set, we don't want the
soc core to un-mute the outputs.

Renamed cs4270_mute() to cs4270_dai_mute() to avoid confusion.
