Subject: drm/amd/display: Remove redundant dsc power gating from init_hw
Git-commit: 95707203407c4cf0b7e520a99d6f46d8aed4b57f
Patch-mainline: v5.18-rc2
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Alt-commit: 75c95f4550e3d4584ff100fef53c240f3291f7cd
[Why]
DSC Power down code has been moved from dcn31_init_hw into init_pipes()
Need to remove it from dcn10_init_hw() as well to avoid duplicated action
on dcn1.x/2.x
[How]
Remove DSC power down code from dcn10_init_hw()
Fixes: 8fa6f4c5715c ("drm/amd/display: fixed the DSC power off sequence during Driver PnP")
