ASoC: tlv320aic32x4: Add gpio configuration to the codec
Add the ability to configure the MFP1->MFP5 registers as GPIOs. In addition adding ALSA controls to get and set the GPIO state. Per the data sheet each MFP can be configured as a GPIO input only, output only or either an input or output. Signed-off-by: Dan Murphy <dmurphy@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
