Description of Changes

Remove the Intel Management Engine Interface (MEI) communication controller from the GPU PCI devices list.
The MEI controller may have different devices within the same IOMMU group, which also need to be added and can vary across different SKUs.Therefore, it is best to drop it for now and add it back if required in the future.
