3bbf99acbd dm: pci: add device table for igd passthrough
The register index and data format of BDSM (Base Data of Stolen Memory)
of Intel integrated graphics is changed in GPU Gen 11. Currently ACRN
uses a long device list for Gen11+ devices. This patch introduces a new
device allowlist for IGD passthrough in igd_pciids.h, covering IGD
device ids from Skylake, and handles passthrough by its generation.

If a device is not listed, it will be treated as a gen 11 device and a
warning will be printed, developers should add the new device to the
list if it is verified to work.
