Arnd Bergmann 7628166d5e tinydrm: add backlight dependency 
Calling devm_of_find_backlight directly means we get a link failure
without CONFIG_BACKLIGHT_CLASS_DEVICE:

drivers/gpu/drm/tinydrm/mi0283qt.o: In function `mi0283qt_probe':
mi0283qt.c:(.text+0x684): undefined reference to `devm_of_find_backlight'

This adds an explicit Kconfig dependency for it. While I did not
observe that failure for st7735r, I assume the same change is needed
there for the same reason.
