drm/amd/display: Remove redundant dsc power gating from init_hw

[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")
