bus/pci: check IOMMU addressing limitation just once

Current code checks if IOMMU hardware reports enough addressing
bits for using IOVA mode but it repeats the same check for any
PCI device present. This is not necessary because the IOMMU hardware
is the same for all of them.

This patch only checks the IOMMU using first PCI device found.
