ARM: dts: omap4-droid4: Add LCD backlight 

The TI LMU driver has not yet been merged, but the device
tree binding for TI LMU drivers has been acked already
earlier by Rob Herring <robh+dt@kernel.org>. So it should
be safe to apply to cut down the number of pending patches.

* REVISIT: Add gpio173 reset pin handling to the driver, see gpio-hog above.
* If the GPIO reset is used, we probably need to have /lib/firmware/maxtouch.fw
