[PATCH v5 13/13] video: Enable VIDEO_DAMAGE for drivers that need it

[Alper Nebi Yasak]

From: Alexander Graf <agraf at csgraf.de>

Some drivers call video_set_flush_dcache() to indicate that they want to
have the dcache flushed for the frame buffer. These drivers benefit from
our new video damage control, because we can reduce the amount of memory
that gets flushed significantly.

This patch enables video damage control for all device drivers that call
video_set_flush_dcache() to make sure they benefit from it.
