drm/amd/display: fix trigger_hotplug to support mst case
[Why & How]
Correct few problems below to have debugfs trigger_hotplug entry
supports mst case
* Adjust the place for acquiring the hpd_lock. We'll also access
dc_link when simulate unplug
* When detect the connector is a mst root, call
reset_cur_dp_mst_topology() to simulate unplug
* Don't support hotplug caused by CSN message since we can't change
mst topology info directly. We can't simulate that
* Clean up redundant code
