d1a2e7004b drm/tinydrm: Replace tinydrm_of_find_backlight with of_find_backlight 
Remove tinydrm_of_find_backlight from tinydrm-helpers.c. We now have
a generic of_find_backlight defined in backlight.c. Let the callers
of tinydrm_of_find_backlight call of_find_backlight. Also, remove
select BACKLIGHT_LCD_SUPPORT and select BACKLIGHT_CLASS_DEVICE from
tinydrm/Kconfig as it is a hack that is no longer needed.
