drm/amd/display: Revert "drm/amd/display: Add flag to detect dpms force off during HPD"
This reverts commit 035f54969bb2c1a5ced52f43e4ef393e0c0f6bfa.
The reverted commit was trying to fix side effect brought by
commit 3c4d55c9b9be ("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 3c4d55c9b9be ("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 3c4d55c9b9be ("drm/amd/display: turn DPMS off on connector unplug")
commit 035f54969bb2 ("drm/amd/display: Add flag to detect dpms force off during HPD")
