drm/omap: fix YUV422 rotation with TILER
TILER rotation with YUV422 pixelformats does not work at the moment. All
other pixel formats work, because the pixelformat's pixel size is equal
to tiler unit size (e.g. XR24's pixel size is 32 bits, and the TILER
unit size that has to be used is 32 bits).
For YUV422 formats this is not the case, as the TILER unit size has to
be 32 bits, but the pixel size is 16 bits. The end result is OCP errors
and sync losts.
This patch adds the code to adjust the variables for YUV422 formats.
We could make the code more generic by passing around the pixel format,
rotation type, angle and the tiler unit size, which would allow us to do
calculations without special case for YUV422. However, this would make
the code more complex, and at least for now this is much more easier to
handle with these two special cases for YUV422.

drm: Remove drm_device->virtdev
This is a leftover from the drm_bus days, where we've had a
bus-specific device type for every bus type in drm_device. Except for
pci (which we can't remove because dri1 drivers) this is all gone. And
the virt driver also doesn't really need it, dev_to_virtio works
perfectly fine.

"Here are some serial and tty fixes for 4.12-rc3. They are a bit bigger
than normal, which is why I had them bake in linux-next for a few
weeks and didn't send them to you for -rc2.
They revert a few of the serdev patches from 4.12-rc1, and bring
things back to how they were in 4.11, to try to make things a bit more
stable there. Rob and Johan both agree that this is the way forward,
so this isn't people squabbling over semantics. Other than that, just
a few minor serial driver fixes that people have had problems with.
All of these have been in linux-next for a few weeks with no reported
issues"
