drm/i915: Engage the DP scramble reset for pipe C on CHV
To get stable CRCs from the DP CRC source we need to reset the scrambler for each frame. Enable the reset feature when grabbing CRCs for pipe C on CHV. Pipes A and B were already covered due sharing the code with VLV. We can safely extend PIPE_SCRAMBLE_RESET_MASK to deal with CHV since the extra bit was MBZ on the older platforms.
