mdss: dsi: Force panel status dead for TE based ESD



Except for TE based ESD, other approaches have a method
to simulate panel dead state by giving following command :

adb shell "echo 5 > /sys/devices/virtual/graphics/fb0/msm_fb_panel_status"

This simulates a display dead state after 5 detections, which is about
25 seconds if the esd detection feature is enabled with periodic
detections every 5 seconds.

This change allows the simulation for TE based ESD approach.
In addition, it also includes the fix to enable BTA/reg read
based ESD thread to be scheduled even in the doze mode.
