[POWERPC] fix iSeries PCI resource management
The way iSeries manages PCI IO and Memory resources is a bit strange
and is based on overriding the content of those resources with home
cooked ones afterward.
This changes it a bit to better integrate with the new resource handling
so that the "virtual" tokens that iSeries replaces resources with are
done from the proper per-device fixup hook, and bridge resources are
set to enclose that token space. This fixes various things such as
the output of /proc/iomem & ioports, among others. This also fixes up
various boot messages as well.
