Currently the plane property doesn't have support for YCBCR_BT2020,
which enables the corresponding color conversion mode on plane CSC.
Enabling the plane property for the planes for GLK & ICL+ platforms.
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.
V4: Combine If-else into single If
V5: Drop the checking for HDR planes and enable YCBCR_BT2020
for platforms GLK & ICL+.
