The Audio has worked, but the mute pin has a weak pulldown which alows
some of the audio signal to pass very quietly.  This patch fixes
that so the mute pin is actively driven high for mute or low for normal
operation.

Fixes: ab8dd3aed011 ("ARM: DTS: Add minimal Support for Logic
PD DM3730 SOM-LV")
