* bootloader/pci.c: Fixed IO remapping so buses >= 1 are remapped.
Reduced PCI space to match bat2. Fixed incorrect region size
calculation in pci_read_bases. Set PCI latency timers to known
sane values. Changed bridge PCI settings to minimum sane instead
of whatever sounded neat in the PCI spec. Force pf regions to
memory mapped to preserve byte access.
