disp: msm: dsi: Panic on getting continuous ESD check failures

During stability stress testing, there are many instances where
the panel is unreachable which results in the ESD check mechanism
failing continuously with PANEL_DEAD events. There are two possible
reasons. Either the device is bad or DSI controller is hung. As of
today, logs/xlog is flooded and info on root cause is missed in the
logs. To catch the root cause for such issues, this patch induces
forced crash when there are five consecutive ESD check failures.
