Currently the plane property doesn't have support for YCBCR_BT2020,
which enables the corresponding color conversion mode on plane CSC.
This propery setting is confined only to HDR Planes as there is
limitation in SDR Planes.
V2: Enabling support for YCBCT_BT2020 for HDR planes on
platforms GLK & ICL
