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.
