Define pcibus_to_node to be able to figure out which NUMA node contains a
given PCI device. This defines pcibus_to_node(bus) in
include/linux/topology.h and adjusts the macros for i386 and x86_64 that
already provided a way to determine the cpumask of a pci device.
x86_64 was changed to not build an array of cpumasks anymore. Instead an
array of nodes is build which can be used to generate the cpumask via
node_to_cpumask.
