Ceri Storey to port-xen, with some additionnal changes by me:
- include bus_dma.c, bus_space.c and pci_machdep.c if pci is defined
instead of dom0ops
- Make various initialisations, and probe/attach pci busses based on NPCI
instead of DOM0OPS
- in conf/files.xen, move xen-specific devices before non-xen specific devices
so that the xen-specific match function is called first, to avoid false
attachement from too liberal match function in non-xen code.
