Subject: [PATCH] Revert "drivers/video/backlight/platform_lcd.c: add support for device tree based probe"

This reverts commit 52e842432f36d5b15227d0ee0d2aa3d2bc3cc0b2.

The DT support never would have worked because there's no platform_data
providing ops. There's not any documented binding for it either.
