Subject: [PATCH 2/4] ASoC: dapm: Fix value setting for _ENUM_DOUBLE MUX's second channel

The value for the second channel in _ENUM_DOUBLE (double channel) MUXs
is not correctly updated, due to using the wrong bit shift.

Use the correct bit shift, so both channels toggle together.

Fixes: 3727b4968453 ("ASoC: dapm: Consolidate MUXs and value MUXs")
