drm/msm/sde: detect ppdone timeouts and issue ctl reset
Add mechanism to detect pingpong done irq timeouts and report
back to CRTC that errors occurred. On reception of a max count
report panel dead event to the CRTC, which currently logs it.
If panic is enabled, ppdone timeout will trigger a register dump
and panic, if panic is not enabled, we try to recover by issuing
a CTL reset before the next kickoff.
