[PATCH 01/12] drm/xe/cri: Add CRI platform definition

[Lucas De Marchi <lucas.demarchi@intel.com>]

From: Balasubramani Vivekanandan <balasubramani.vivekanandan@intel.com>

Add platform definition and PCI IDs for Crescent Island.

Other platforms use INTEL_VGA_DEVICE since they have a
PCI_BASE_CLASS_DISPLAY class.  This is not the case for CRI, so just
match on devid, which should be sufficient.
