gpiolib: Force wm831x GPIOs into GPIO mode when requested
This is the chip default but it's possible the bootloader or OTP will have been configured to a different mode (eg, to provide feedback during startup). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
