In order to use computed config for DP SDPs (DP VSC SDP and DP HDR Metadata
Infoframe SDP), it replaces intel_dp_vsc_enable() function and
intel_dp_hdr_metadata_enable() function to intel_dp_set_infoframes()
function.
Before applying it, routines of program SDP always calculated configs when
they called. And it removes unused functions.
