When running "make oldconfig" on a .config where CONFIG_BACKLIGHT_LCD_SUPPORT is not set, two new config options ("Lowlevel LCD controls" and "Lowlevel Backlight controls") appear, both defaulting to "m".

Drop the "default m", as options should default to disabled, and because several driver config options already select LCD_CLASS_DEVICE or BACKLIGHT_CLASS_DEVICE when needed.
