powerpc/4xx: Add pcix type 1 transactions

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

Some of the newer 4xx pci cores need an explicit bit set to send
type 1 transactions instead of just comparing the bus numbers.

This patch enables type 1 transations for pcix nodes, thus enabling
devices behind PCI bridges.
