Subject: [PATCH] [ALSA] soc - tlv320aic3x - add GPIO support

This patch adds support for AIC3x GPIO lines. They can be configured for
many possible functions as well as be driven manually. I also introduced
i2c read functionality since the GPIO state register has to be read from
hardware every time and can not be served from cache.
