There are still missing corner cases with cursor interaction and these
fast plane updates on Picasso and Raven2 leading to endless PSTATE
warnings for typical desktop usage depending on the userspace.

This change should be reverted until these issues have been resolved.

496091fa04 drm/amd/display: Fix null-deref on vega20 with xgmi 
[Why]
After clkmgr rework it gets initialized after resource pool.
The clkmgr is used in resource pool init for xgmi path.
That causes driver crash on Vega20 with xgmi due to NULL deref.

[How]
Move xgmi compensation code to dce121_clk_mgr_construct()
That also allows to make dce121_clock_patch_xgmi_ss_info()

This reverts commit 06b89b38f3.
This fix is not proper. allocate_mqd can't be moved before
allocate_sdma_queue as it depends on q->properties->sdma_id
set in later.
