msm: mdss: fix ambient mode screen freeze issue
When enter ambient mode,mipi will change from normal to stop.
panel will switch to video mode due to the floating signal
sometimes,then screen will freeze.
Enable ULPS,when enter ambient mode,mipi will change to ULPS and
then to stop,this will indicate the panel to enter idle mode safely.
When enable ULPS,the screen image will shift due to mipi footswitch
off.Keep MIPI footswitch on to avoid this issue.
