Pull more drm updates from Dave Airlie:
"Looks like I missed a tegra feature request for next, but should still
be fine since it's pretty self contained.
Apart from that got a set of i915 and amdgpu fixes as per usual along
with a few misc fixes.
tegra:
- Tegra186 hardware cursor support
- better capability reporting for different SoC
- better framebuffer modifier support
- host1x fixes
ttm:
- fix unswappable BO handling
efifb:
- check for PCI before using it
amdgpu:
- Fixes for Aldebaran
- Display LTTPR fixes
- eDP fixes
- Fixes for Vangogh
- RAS fixes
- ASPM support
- Renoir SMU fixes
- Modifier fixes
- Misc code cleanups
- Freesync fixes
i915:
- Several fixes to GLK handling in recent display refactoring
- Rare watchdog timer race fix
- Cppcheck redundant condition fix
- Overlay error code propagation fix
- Documentation fix
- gvt: Remove one unused function warning
- gvt: Fix intel_gvt_init_device() return type
- gvt: Remove one duplicated register accessible check"
