David Lechner 8941a7cbcc 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.

Drm has no monochrome or greyscale support so add a conversion
from the common format XR24.

Also reorder includes into the common order.

BACKLIGHT_CLASS_DEVICE was selected in the last version of the
tinydrm patchset to fix the backlight dependency, but the
ifdef CONFIG_BACKLIGHT_CLASS_DEVICE was forgotten. Fix that.
