Hive ID is used during copy path selection to locate an optimal
pool of SDMA engines. However, for CPU-GPU connections we always
want to use the host port facing engines, known generally as the
PCIe optimzed engines. We want this selection even when the
connection is XGMI hence dropping the hive id for CPUs.
