  Currently, we are calling fill_dc_dirty_rects() even if PSR isn't
supported by the relevant link in amdgpu_dm_commit_planes(), this is
undesirable especially because when drm.debug is enabled we are printing
messages in fill_dc_dirty_rects() that are only useful for debugging PSR
(and confusing otherwise). So, we can instead limit the filling of dirty
rectangles to only when PSR is enabled.

v2: give a more concrete reason.
