drm/amd/display: Always use legacy way of setting cursor on DCE

Browse Source 
Some IGT tests fail with the new atomic cursor updates
when running on older DCE-based ASICs. To work around
these issues keep calling the amdgpu_dm_commit_cursors
for each cursor update on DCE, even if those cursor
updates coincide with other plane updates.
