Monitors like LG 27UL650-W, 27UK850 goes into power sleep state
and generates long duration hotplug events even when the monitor
is connected for display. Here is a proposal to detect and
suppress such hotplug events by "sleep" for 2 secs for power
state monitor become available before enable atomic commit.
A debugfs entry is created to enable the suppression of the
hotplug event in such scenarios.
