Pull drm fixes from Dave Airlie:
"This is the weekly fixes for rc4. Misc fixes across rockchip, imx,
amdgpu and i915.

The biggest change is for amdkfd where the trap handler needs an
updated fw from a header which makes it a bit larger. I hadn't noticed
this particular file before so I'm going to figure out what the magic
is for, but the fix should be fine for now.

amdgpu:
- DCN 3.1.4 fixes
- DCN 3.2.x fixes
- GC 11.x fixes
- Virtual display fix
- Fail suspend if resources can't be evicted
- SR-IOV fix
- Display PSR fix

amdkfd:
- Fix possible NULL pointer deref
- GC 11.x trap handler fix

i915:
- Add locking around DKL PHY register accesses
- Stop abusing swiotlb_max_segment
- Filter out invalid outputs more sensibly
- Setup DDC fully before output init
- Simplify intel_panel_add_edid_alt_fixed_modes()
- Grab mode_config.mutex during LVDS init to avoid WARNs

rockchip:
- fix probing issues
- fix framebuffer without iommu
- fix vop selection
- fix NULL ptr access

imx:
- Fix Kconfig
- fix mode_valid function"
