[igt-dev] [PATCH igt 2/4] lib/intel_chipset: Add Lunar Lake support

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

Add basic definition for the Lunar Lake platform. This uses the PCI ID
from the xe_pciids.h which has a macro in a slighlty different form.

Going forward we could also trim down a little bit the the info struct
like was done in the kernel, relying on gmdid and IP version checks.
This is left for later.
