Merge branch 'drm-next-4.20' of git://people.freedesktop.org/~agd5f/linux into drm-next

This is a new pull for drm-next on top of last weeks with the following
changes:
- Fixed 64 bit divide
- Fixed vram type on vega20
- Misc vega20 fixes
- Misc DC fixes
- Fix GDS/GWS/OA domain handling

Previous changes from last week:
amdgpu/kfd:
- Picasso (new APU) support
- Raven2 (new APU) support
- Vega20 enablement
- ACP powergating improvements
- Add ABGR/XBGR display support
- VCN JPEG engine support
- Initial xGMI support
- Use load balancing for engine scheduling
- Lots of new documentation
- Rework and clean up i2c and aux handling in DC
- Add DP YCbCr 4:2:0 support in DC
- Add DMCU firmware loading for Raven (used for ABM and PSR)
- New debugfs features in DC
- LVDS support in DC
- Implement wave kill for gfx/compute (light weight reset for shaders)
- Use AGP aperture to avoid gart mappings when possible
- GPUVM performance improvements
- Bulk moves for more efficient GPUVM LRU handling
- Merge amdgpu and amdkfd into one module
- Enable gfxoff and stutter mode on Raven
- Misc cleanups
