It adds new enumeration definitions for VSC SDP Payload for Pixel Encoding/Colorimetry Format.
enum dp_colorspace and enum dp_colorimetry correspond "Pixel Encoding and Colorimetry Formats". enum dp_dynamic_range corresponds "Dynamic Range". And enum dp_content_type corresponds "Content Type" All of them are based on DP 1.4 spec [Table 2-117: VSC SDP Payload for DB16 through DB18].
