What is the alignment of those regions then? None? And do regions of

These PCI controllers make separate calls to
cpu_register_physical_memory() for separate callbacks. Reading
ppce500_pci_init(), for example:
0xe0008000 -> CFGADDR (4 bytes)
0xe0008004 -> CFGDATA (4 bytes)
0xe0008c00 -> other registers
That's goofy. If the single device owns the entire region, it should
region the entire region instead of relying on subpage functionality.
If just requires a switch() on the address to dispatch to the
appropriate functions. It should be easy enough to fix.
