[media] timblogiw: move to staging in preparation for removal
The Timberdale FPGA video driver has not seen any real development
since 2011 (and very little before that).
One of the problems with the timblogiw driver is that it uses videobuf
instead of the newer vb2 framework. The long term goal is to either
convert or remove any driver still using videobuf. Since none of the
core v4l developers has the hardware, we cannot convert it ourselves.
As far as I can tell it was only used in an Intel demo board in 2009
using Meego:
http://www.chinait.com/intelcontent/intelprc/admin/PDFFile/
20106411545.pdf
which has since been superseded.
Moving this driver to staging is the first step towards removal. After 2 or
3 kernel cycles it will be removed altogether unless someone steps up to
clean up this driver.

drm/vc4: Add a proper short-circut path for legacy cursor updates.
Previously, on every modeset we would allocate new display list
memory, recompute changed planes, write all of them to the new memory,
and pointed scanout at the new list (which will latch approximately at
the next line of scanout). We let
drm_atomic_helper_wait_for_vblanks() decide whether we needed to wait
for a vblank after a modeset before cleaning up the old state and
letting the next modeset proceed, and on legacy cursor updates we
wouldn't wait. If you moved the cursor fast enough, we could
potentially wrap around the display list memory area and overwrite the
existing display list while it was still being scanned out, resulting
in the HVS scanning out garbage or just halting.
Instead of making cursor updates wait for scanout to move to the new
display list area (which introduces significant cursor lag in X), we
just rewrite our current display list.

drm/vc4: Move the plane clipping/scaling setup to a separate function.
As we add actual scaling, this is going to get way more complicated.
