ASoC: ab8500: Skip missing DMIC GPIOs on AB8505

Browse source

GPIO27, GPIO29 and GPIO31 provide the digital microphone clock
outputs on AB8500, but these GPIOs do not exist on AB8505. The shared
codec driver nevertheless accesses their direction register while
setting up every AB8505 codec.

Identify the parent MFD device and leave the nonexistent GPIOs
untouched on AB8505.
