nb/amd/pi/00730F01: assign IOMMU ops in chipset devicetree
Since the IOMMU is always function 2 of device 0 on bus 0, the device
operations can be statically assigned in the devicetree and there's no
need to bind the IOMMU device operations to the PCI device during
runtime via a list of PCI IDs.
TEST=PC Engines APU2 still boots and doesn't show any new problems
