mfd: Provide platform data for WM831x GPIO configuration

Allow the GPIO mode of WM831x devices to be configured using platform data.
Users may provide a table of GPIO register values in gpio_defaults[]. In
order to allow 0 to be set explicitly out of range values are accepted and
masked off, with a WM831X_GPIO_CONFIGURE define provided to set an out of
range value.

This can be used to configure higher numbered GPIOs or override values set
in OTP for GPIOs configured using OTP.
