Merge branch 'drm-next-5.1' of git://people.freedesktop.org/~agd5f/linux into drm-next

New stuff for 5.1.
amdgpu:
- DC bandwidth formula updates
- Support for DCC on scanout surfaces
- Support for multiple IH rings on soc15 asics
- Fix xgmi locking
- Add sysfs interface to get pcie usage stats
- Simplify DC i2c/aux code
- Initial support for BACO on vega10/20
- New runtime SMU feature debug interface
- Expand existing sysfs power interfaces to new clock domains
- Handle kexec properly
- Simplify IH programming
- Rework doorbell handling across asics
- Drop old CI DPM implementation
- DC page flipping fixes
- Misc SR-IOV fixes

amdkfd:
- Simplify the interfaces between amdkfd and amdgpu

ttm:
- Add a callback to notify the driver when the lru changes

sched:
- Refactor mirror list handling
- Rework hw fence processing
