[POWERPC] Let subordinate transparent bridges be transparent.



In pcibios_fixup_bus(), bridges that are subordinate
to transparent bridges were still relocating their
IORESOURCE_IO and IO_RESOURCE_MEM start and end values.

Fix this by preventing the transparent bridge from
relocating the start and end values, thus allowing the
subordinate non-transparent bridge full molestation rights.
