declare 1-to-1 mapping for PCI bus address space

On Coreboot, the PCI bus address space has identity mapping with the
physical address space, so declare it as such to ensure that the "pci_map_bar"
function used by some PCI drivers is behaving properly.

This fixes the EHCI PCI driver initialization on Stumpy.
