ASoC: dapm: Introduce DAPM_DOUBLE_R dual channel dual register control type 



A DAPM_DOUBLE_R control type can be used for dual channel mixer input
selectors / mute controls across 2 registers, possibly toggling both
channels together.

The control is meant to be shared by 2 widgets, 1 for each channel,
such that the mixer control exposed to userspace remains a combined
stereo control.
