drm/msm/dp: replug event is converted into an unplug followed by an plug events
Remove special handling of replug interrupt and instead treat replug event
as a sequential unplug followed by a plugin event. This is needed to meet
the requirements of DP Link Layer CTS test case 4.2.1.3.
Changes in V2:
-- add fixes statement
Changes in V3:
-- delete EV_HPD_REPLUG_INT
Fixes: f21c8a276c
