ASoC: wm9712/wm9713: Replace virtual registers with custom put/get callbacks
The wm9712/wm9713 has separate mixers for the left and the right channel, but the inputs to the mixers are enabled/disabled by the same control. Currently this is implemented by the driver by registering two virtual controls for each physical control, one for the left mixer and one for the right mixer. Using virtual registers will no longer work when the driver has been converted to regmap. This patch converts the driver to use controls with custom put/get callbacks instead which implement the logic making sure that the physical control is unmuted when either the left or the right control is unmuted.
