mfd: Conditionally add WM831x backlight subdevice
The WM831x backlight driver requires at least the specification of the current sink to use and a maximum current to allow them to function and will actively interfere with other users of the regulators it uses if misconfigured so only register the subdevice for it if this platform data has been supplied.
