If the drm_plane has a source width that's greater than the max width
supported by a single hw overlay, then we assign a 'r_overlay' to it in
omap_plane_atomic_check().
Both overlays should have the capabilities required to handle the source
framebuffer. The only parameters that vary between the left and right
hwoverlays are the src_w, crtc_w, src_x and crtc_x as we just even chop
the fb into left and right halves.
We also take care of not creating odd width size when dealing with YUV
formats.
Since both halves need to be 'appear' side by side the zpos is
recalculated when dealing with dual overlay cases so that the other
planes zpos is consistent.
Depending on user space usage it is possible that on occasion the number
of requested planes exceeds the numbers of overlays required to display
them. In that case a failure would be returned for the plane that cannot
be handled at that time. It is up to user space to make sure the H/W
resource are not over-subscribed.

This adds the required infrastructure for manually updated displays,
such as DSI command mode panels. While those panels often support
partial updates we currently always do a full refresh.
The display will be refreshed when something calls the dirty callback,
such as libdrm's drmModeDirtyFB(). This is currently being done at least
by the kernel console and Xorg (with modesetting driver) in their
default configuration. Weston does not implement this and the fbdev
backend does not work (display will not update). Weston's DRM backend
uses double buffering and the page flip will also trigger a display
refresh.

drm_format_num_planes() is basically a lookup in the drm_format_info table
plus an access to the num_planes field of the appropriate entry.
Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to drm_format_num_planes is therefore more efficient.
Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.

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.

We have three rotation methods supported by the SoCs with DSS: DMA,
VRFB and TILER.
DMA rotation works in theory on all DSS platforms, but in practice it's
unusable due to the huge amount of memory bandwidth it uses, and has
never really been used.
VRFB is available on OMAP3, but is not supported by omapdrm, even though
we have some code for it in the dispc driver.
TILER is supported on OMAP4/OMAP5/DRA7/AM5 platforms, but has some
driver bugs.
To clean up the driver to help fixing the TILER issues, this patch drops
the DMA and VRFB rotation support, leaving only TILER rotation.

Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI
as a convenience.
Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
through the atomic API, but realizing that userspace is likely to take
shortcuts and assume that the enum values are what is sent over the
wire.
As a result these defines are provided purely as a convenience to
userspace applications.
Changes since v3:
- Switched away from past tense in comments
- Add define name change to previously mis-spelled DRM_REFLECT_X comment
- Improved the comment for the DRM_MODE_REFLECT_<axis> comment
Changes since v2:
- Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_
- Fix compilation errors
- Changed comment formatting
- Deduplicated comment lines
- Clarified DRM_MODE_PROP_REFLECT_ comment
Changes since v1:
- Moved defines from drm.h to drm_mode.h
- Changed define prefix from DRM_ to DRM_MODE_PROP_
- Updated uses of the defines to the new prefix
- Removed include from drm_rect.c
- Stopped using the BIT() macro

pixels. Given that all supported formats use the same number of bytes
per pixel in all planes, framebuffer creation checks can be simplified.
