Might be nice to switch this over to using igt_plane_has_format_mod().
We'd need to push it down a bit further since we'd need to query each
plane in turn.

Alternatively we could do something a bit simpler:
igt_require(igt_display_has_format_mod(display, DRM_FORMAT_XRGB888,
				       tiling));
igt_require(igt_display_has_format_mod(display, DRM_FORMAT_ARGB888,
				       LOCAL_DRM_FORMAT_MOD_LINEAR));
