drm/amd/display: Revert "drm/amd/display: turn DPMS off on connector unplug"

This reverts commit 3c4d55c9b9becedd8d31a7c96783a364533713ab.

Revert the commit because:
- It's incomplete of the function dm_set_dpms_off() for mst case.  For
  stream sinks whithin the same mst topology, they share the same dc_link.
  dm_set_dpms_off() tries to update one mst stream only which is
  incomplete.
- Setting dpms off should be triggered by usermode. Besdies, it seems
  usermode does release relevant resource for mst & non-mst case when
  unplug connecotr now.
