Rob Herring 79de36042e powerpc/isa-bridge: Fix ISA mapping when "ranges" is not present 
Commit e4ab08be5b ("powerpc/isa-bridge: Remove open coded "ranges"
parsing") broke PASemi Nemo board booting. The issue is the ISA I/O
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.
