Merge branch 'drm-next-4.19' of git://people.freedesktop.org/~agd5f/linux into drm-next 

More features for 4.19:
- Use core pcie functionality rather than duplicating our own for pcie
  gens and lanes
- Scheduler function naming cleanups
- More documentation
- Reworked DC/Powerplay interfaces to improve power savings
- Initial stutter mode support for RV (power feature)
- Vega12 powerplay updates
- GFXOFF fixes
- Misc fixes
