Instead of using a custom binding for retrieving the GPIO that activates the
LCD from devicetree, use a standard regulator.

This approach has the advantage to be more generic.

For example: in the case of a board that has a PMIC supplying the LCD voltage,
the current approach would not work, as it only searches for a GPIO pin.

Use videomode helpers to get display timings and configurations from
device tree when platform_data is absent.

Add a simple device tree probe support for mxsfb driver.  Before
a common binding for struct fb_videomode is available, the driver will
keep using struct mxsfb_platform_data.  That said, platform code will
use auxdata to attach mxsfb_platform_data for device tree boot.

Now that there is a Documentation/devicetree hierarchy, and the driver in
question has no specific platform dependency, move the binding
information to a more appropriate place.
