By using the modifier plane capability flags to encode the modifiers' CCS type and tiling attributes, it becomes simpler to the check for any of these capabilities when providing the list of supported modifiers. This also allows distinguishing modifiers on future platforms where platforms with the same display version support different modifiers. An example is DG2 and ADLP, both being D13, where DG2 supports only F and X tiling, while ADLP supports only Y and X tiling. With the INTEL_PLANE_CAP_TILING_* flags added in this patch we can provide the correct modifiers for each platform. v2: - Define PLANE_HAS_* with macros instead of an enum. (Jani) - Rename PLANE_HAS_*_ANY to PLANE_HAS_*_MASK. (Jani) - Rename PLANE_HAS_* to INTEL_PLANE_CAP_*. - Set the CCS_RC_CC cap only for DISPLAY_VER >= 12. - Set the TILING_Y cap only for DISPLAY_VER < 13 || ADLP. - Simplify the SKL plane cap display version checks and move them to a separate function.
