Commit e4ab08be5b49 ("powerpc/isa-bridge: Remove open coded "ranges"

range was not getting mapped as the logic to handle no "ranges" was
inverted. If phb_io_base_phys is non-zero, then the ISA range defaults
to the first 64K of the PCI I/O space. phb_io_base_phys should only be 0
when looking for a non-PCI ISA region.

Applied to powerpc/fixes.
