The recent code in prep_pci.c no longer tweaks pci memory resources to fit
into a 256 MByte BAT range. For some reason this is now limited I/O resources.
I don't know why this change was introduced. The attached diff keeps the handling
for I/O and introduces a similar fix for memory. I don't know if this is the
way to do it. The ncr810 controller starts working again.
