This patch series cleanup unused code by eliminating it at compile time
and then enable usage of all 256 PCI buses per every PCI domain as
currently PCI bus numbers have to be unique across all PCI domains.
So first bus number of each PCI domain would be zero and not the bus
number of the previous domain plus one. As such bus assignment changes
BDF address of every PCI device on multi-domain system, this new
"feature" is configurable by config option to prevent regressions.

Applied to powerpc/next.
