drm: Add DisplayPort colorspace property creation function
Because between HDMI and DP have different colorspaces, it adds drm_mode_create_dp_colorspace_property() function for creating of DP colorspace property. v3: Addressed review comments from Ville - Add new colorimetry options for DP 1.4a spec. - Separate set of colorimetry enum values for DP. v4: Add additional comments to struct drm_prop_enum_list. Polishing an enum string of struct drm_prop_enum_list v5: Change definitions of DRM_MODE_COLORIMETRYs to follow HDMI prefix and DP abbreviations. Add missed variables on dp_colorspaces. Fix typo. [Uma] v6: Addressed review comments from Ilia and Ville - Split drm_mode_create_colorspace_property() to DP and HDMI connector. v7: Fix typo [Jani Saarinen] Fix white space. v8: Addressed review comments from Ville - Drop colorimetries which have another way to distinguish or which would not be used. v9: Addressed review comments from Ville - Split hunk into renaming and adding of code.
