Merge tag 'drm-next-5.5-2019-11-15' of git://people.freedesktop.org/~agd5f/linux into drm-next

drm-next-5.5-2019-11-15:

amdgpu:
- Fix AVFS handling on SMU7 parts with custom power tables
- Enable Overdrive sysfs interface for Navi parts
- Fix power limit handling on smu11 parts
- Fix pcie link sysfs output for Navi
- Probably cancel MM worker threads on shutdown

radeon:
- Cleanup for ppc change
