gpio: Add WM831X GPIO driver

Add support for the GPIO pins on the WM831x. No direct support is
currently supplied for configuring non-gpiolib functionality such
as pull configuration and alternate functions, soft configuration
of these will be provided in a future patch.

Currently use of these pins as interrupts is not supported due to
the ongoing issues with generic irq not support interrupt controllers
on interrupt driven buses. Users can directly request the interrupts
with the wm831x-specific APIs currently provided if required.
