ASoC: dapm: Introduce DAPM_DOUBLE dual channel control type
A DAPM_DOUBLE control type can be used for dual channel mixer input selectors / mute controls in one register, 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.
