In order to readout DP SDPs (Secondary Data Packet: DP HDR Metadata
Infoframe SDP, DP VSC SDP), it refactors handling DP SDPs codes.
It adds new compute routines for DP HDR Metadata Infoframe SDP
and DP VSC SDP. 
And new writing routines of DP SDPs (Secondary Data Packet) that uses
computed configs.
New reading routines of DP SDPs are added for readout.
It adds a logging function for DP VSC SDP.
When receiving video it is very useful to be able to log DP VSC SDP.
This greatly simplifies debugging.
In order to use a common VSC SDP Colorimetry calculating code on PSR,
it uses a new psr vsc sdp compute routine.

Gwan-gyeong Mun (18):
