[0/3] Clean up RK3328 audio codec GPIO control

Hi all,

Investigating the RK3328 GPIO_MUTE pin in the context of boards that use
it to control a regulator has highlighted that the audio codec driver
currently has some hard-coded implicit control of that pin. Fortunately
those boards don't currently enable the audio codec, because it would be
pretty terrible if playing audio changed the SD card I/O voltage. This
is a first crack at making things better.

Robin.
