Convert Mediatek ASoC codecs to use GPIO descriptors

Merge series from Linus Walleij <linus.walleij@linaro.org>:

Convert over the Mediatek codecs to use GPIO descriptors.

One few-liner affects gpiolib-of.h, I don't think there
will be conflicts so I suggest that all of this can be
merged through ASoC after review.
