Options

Merge https://gitlab.freedesktop.org/drm/msm into drm-next-msm-5.8 

* new gpu support: a405, a640, a650
* dpu: color processing support
* mdp5: support for msm8x36 (the thing with a405)
* some prep work for per-context pagetables (ie the part that
  does not depend on in-flight iommu patches)
* last but not least, UABI update for submit ioctl to support
  syncobj (from Bas)
