Currently the plane property doesn't have support for YCBCR_BT2020,
which enables the corresponding color conversion mode on plane CSC.
In ICL+ platforms , this property setting is confined only to HDR
Planes as there is limitation in SDR Planes and while in GLK it
set for all planes.
V2: Enabling support for YCBCT_BT2020 for HDR planes on
platforms GLK & ICL
V3: Refined the condition check to handle GLK & ICL+ HDR planes
Also added BT2020 handling in glk_plane_color_ctl.
