Merge v7.0-rc7 into drm-next

Thomas Zimmermann needs 2f42c1a61616 ("drm/ast: dp501: Fix
initialization of SCU2C") for drm-misc-next.

Conflicts:
- drivers/gpu/drm/amd/display/dc/hwss/dcn401/dcn401_hwseq.c

Just between e927b36ae18b ("drm/amd/display: Fix NULL pointer
dereference in dcn401_init_hw()") and it's cherry-pick that confused
git.

- drivers/gpu/drm/amd/pm/swsmu/smu11/smu_v11_0.c

Deleted in 6b0a6116286e ("drm/amd/pm: Unify version check in SMUv11")
but some cherry-picks confused git. Same for v12/v14.
