pci_scan_bus start
PCI: pci_scan_bus for bus 00
PCI: scan devfn 0x0 to 0xff
PCI: devfn 0x0
PCI: pci_scan_bus pci_scan_get_dev returns dev <NULL>

Change dts compiler to emit a new struct member, dtsname, for devices,
so we can get actual useful names for things. 

Several mods and printks added. 

printk(BIOS_SPEW
gives no output for reasons I don't understand. 

Next in line is bringing back v2 support for pci, but not doing it the
way v2 does it. 

note the cpus() printk above. cpus don't have a valid path yet. 

We still need to work out the dts syntax for systems with multiple links
