No functional changes in this patch.
The SDP Header is a generic header for secondary data packets for
both eDP and DP so call it dp_sdp_header. This header gets used for
different SDP types already defined.
Also header bytes 2 and 3 are secondary data packet specific header bytes.
So change the comment to indicate the same.
