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.

drm/tinydrm: Generalize tinydrm_xrgb8888_to_gray8()
...
This adds parameters for vaddr and clip to tinydrm_xrgb8888_to_gray8() to
make it more generic.
dma_buf_{begin,end}_cpu_access() are moved out to the repaper driver.
Return type is change to void to simplify error handling by callers.

tinydrm patchset to fix the backlight dependency, but the
ifdef CONFIG_BACKLIGHT_CLASS_DEVICE was forgotten. Fix that.
