drm/amd/display: Add connector HPD trigger debugfs entry
[why]
Need a tool to retrigger a virtual hotplug for testing purposes with
force redetection in both DC and DM.
[how]
Emulate handle_hpd_irq for connector as if usermode would trigger
a hotplug. Perform DC link discovery, DM connector update, and
DM force atomic commit.
In order to trigger HPD on the connector user needs to echo 1 into
"trigger_hotplug" debugfs entry on its respective connector.
