PCI fixes
Only set the PIR table signature and checksum in the init function -
that way, if it is disabled at runtime (eg, due to coreboot) then
it wont be found by the OS.
Fix parameter swap bug in handle_1ab102.
Add support for more than one bus in pci scanning code (but only have
1 bus for now).
