ASoC: ac97: add gpio chip
The AC97 specification provides a guide for 16 GPIOs in the codecs. If the gpiolib is compiled in the kernel, declare a gpio chip. This was tested with a pxa27x board (mioa701) and a wm9713 codec. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
