[RFC PATCH v1 00/12] drm/msm/dpu: support virtual wide planes

[Dmitry Baryshkov]

As promised in the basic wide planes support ([1]) here comes a series
supporting 2*max_linewidth for all the planes.

Note: Proper support for rot90 is pending. Granted that it is only
enabled on sc7280 and it only supports UBWC (tiled) framebuffers, it was
quite low on my priority list. I plan to get it done for v2.

Note#2 to simplify the dpu_plane_virtual_assign_resources(), which
already becomes big enough, I stripped support for sharing the SSPP
across two planes (doubling amount of planes available to some of
compositors/applications). I plan to get back to this topic once this
series lands.

Dependencies: msm-next + msm-fixes, [1], [2]
