DP2.1 specification says:
"The DP Source device shall retransmit an active video image after
detecting any PR error status bits set in the PANEL REPLAY ERROR STATUS
register (DPCD 02020h) unless the DP Source device is already updating an
entire active video image."
This patch set is implementing deactivation/activation of Panel Replay
on errors. Also ALPM error handling for eDP Panel Replay is added.
