7cfe56172a ASoC: wm8903: Expose GPIOs through gpiolib
Also, update platform_data GPIO handling to have an explicit "don't
touch this pin" option.

Add #defines for the GPIO pin functions.

37f88e8407 ASoC: Initial WM8903 microphone bias and short detection
Provide support for WM8903 microphone presence and short detection
using the GPIOs to route out a logic signal suitable for handling
using snd_soc_jack_add_gpios() on the processor GPIOs.

73b34ead74 ASoC: Add GPIO configuration support for WM8903
Allow users to pass in a default configuration for the GPIOs of
the WM8903 as platform data. This allows configuration of the pin
muxing of the device.
