Subject: [PATCH] Force modesetting for AlderLake-P and RaptorLake-P with Xe
 graphics

On Intel AlderLake-P and RaptorLake-P CPUs with Xe graphics, the intel DDX driver
with Iris DRI actually doesn't work correctly with 3D graphics, while the modesetting driver does.
Force modesetting auto-switching for these cards when no xorg.conf is provided.
