drm/msm/sde: handle esd recovery in sde encoder

Panel may stop sending TE signal when esd check
fail. That leads to pp timeout and rsc in hang
state. RSC hang state can be avoid by changing
the vsync source to watchdog timer. Vsync source
reset to panel TE when DRM client reset the
display after receiving the panel dead event.
PingPong timeout should also trigger the retire
fence during esd failure because ctl_start IRQ
might be missed.
