[PATCH] ARM: DTS: omap4-sdp: Add regulator for LCD backlight (pwm-backlight)

Since in DT booted kernel dummy regulators are no longer supported we need
to provide valid phandle for the regulator needed by the backlight.
On the board VBAT is used to power the LCD backlight(s).

Hi,

This patch is needed for 3.13 to get the LCD backlight to work again.

Regards,
Peter
