Patch-mainline: v4.15-rc1
References: FATE#322643 bsc#1055900

Add defines for the secondary data packet (SDP) types from the spec.
These are the DP specific ones, and in addition HDMI infoframe types
(see enum hdmi_infoframe_type) are also valid SDP types.

V2: Add more SDP types
V3: Note the DP version that added each SDP type (Rodrigo)
