mfd: Add basic device tree binding for wm8994 Add a placeholder device tree binding for the wm8994 driver. At present the binding is essentially null as none of the platform data is supported, and at least some of that will depend on the pending regulator bindings.

WM1811/WM8994/WM8958 audio CODEC
These devices support both I2C and SPI (configured with pin strapping
on the board).
Required properties:
mfd: wm8994: Add some OF properties Add properties for some of the more important bits of platform data and fill out the binding document. Not all of the current platform data is suitable for the sort of fixed configuration that is done using DT, some of it should have runtime mechanisms added instead and some is unlikely to ever be used in practical systems.

- gpio-controller : Indicates this device is a GPIO controller.
- #gpio-cells : Must be 2. The first cell is the pin number and the
second cell is used to specify optional parameters (currently unused).
- AVDD2-supply, DBVDD1-supply, DBVDD2-supply, DBVDD3-supply, CPVDD-supply,
SPKVDD1-supply, SPKVDD2-supply : power supplies for the device, as covered
in Documentation/devicetree/bindings/regulator/regulator.txt
Optional properties:
- interrupts : The interrupt line the IRQ signal for the device is
connected to. This is optional, if it is not connected then none
of the interrupt related properties should be specified.
- interrupt-controller : These devices contain interrupt controllers
and may provide interrupt services to other devices if they have an
interrupt line connected.
- interrupt-parent : The parent interrupt controller.
- #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
The first cell is the IRQ number.
The second cell is the flags, encoded as the trigger masks from
