Sankeerth Billakanti 7424c2352d disp: msm: dp: clear notification states for dp mst
If a DP MST display is connected after a DP SST unplug, the
DISCONNECT_NOTIFIED state is not cleared and CONNECT_NOTIFIED
state is not set. These states are not relevant for DP MST and
hence skipped during the send_notification. But the
DISCONNECT_NOTIFIED state that was not cleared from the previous
SST unplug will prevent the wait for completion when DP MST is
disconnected. This will trigger the host_unready to get executed
before the dp_display_disable happens for the DP MST displays.
As the result, the dp_display_disable exits early causing all the
stream clocks and the panels objects to remain active even after
unplug.

As CONNECT_NOTIFIED and DISCONNECT_NOTIFIED state are not relevant
for DP MST, clearing them if DP MST hpd detected in dp_display.
