drm/amd/display: Add trigger connector unplug
[why]
We need a virtual tool that would emulate a physical
connector unplug to usermode, while connector is
still physically plugged in.
[how]
Added a new option to debugfs entry "trigger_hotplug".
It emulates hotplug irq handling scenario by clearing
DC and DM connector states.
It can be triggered with the following command:
echo 0 > /sys/kernel/debug/dri/0/DP-X/trigger_hotplug
