This change adds a debug node named 'crc' to drm_dp to read the frame CRC values for DP controller and DP Sink. In order to facilitate the immediate read of the CRC values when accessed, it enables the CRC calculation on the controller and sink automatically when the stream is enabled. In addition to the frame CRC values it also reads the MISR values from controller and PHY to validate the data flow from controller to PHY.
