drm/fourcc: define Intel Xe2 related tile4 ccs modifiers
Add Tile4 type ccs modifiers to indicate presence of compression on Xe2. Here is defined I915_FORMAT_MOD_4_TILED_LNL_CCS which is meant for integrated graphics with igpu related limitations Here is also defined I915_FORMAT_MOD_4_TILED_BMG_CCS which is meant for discrete graphics with dgpu related limitations Signed-off-by: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Acked-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240816115229.531671-3-juhapekka.heikkila@gmail.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
