Merge branch 'for-upstream/hdlcd' of git://linux-arm.org/linux-ld into drm-next

From: Liviu Dudau <Liviu.Dudau@arm.com>
"I managed to loose track of a few patches for HDLCD while focusing
on Mali DP and found them again when investigating an issue with
the way HDLCD behaves on teardown. They can go into drm-next for
one of the v4.19-rcX if you're not going to do another pull request
before the merge window."
