drm/amd/display: Revert "drm/amd/display: Add flag to detect dpms force off during HPD"

Browse Source 
This reverts commit 035f54969b.

The reverted commit was trying to fix side effect brought by
commit 3c4d55c9b9 ("drm/amd/display: turn DPMS off on connector unplug")

However,
* This reverted commit will have mst case never call dm_set_dpms_off()
  which conflicts the idea of original commit 3c4d55c9b9 ("drm/amd/display: turn DPMS off on connector unplug")
  That's due to dm_crtc_state is always null since the input parameter
  aconnector is the root device (source) of mst topology.  It's not an
  end stream sink within the mst topology.
* 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. Which means we no longer need both commits now:
  commit 3c4d55c9b9 ("drm/amd/display: turn DPMS off on connector unplug")
  commit 035f54969b ("drm/amd/display: Add flag to detect dpms force off during HPD")
