Log Message:
Jetson TK1 u-boot sets up PCI IO space in an impossible-to-use
configuration.  As we're already allocating resources on the PCI
bus, set up our own mapping of PCI address spaces into the ARM
address space.  We rely on a potential overlap of address space
windows to allow us to use the same bus_space_tag for PCI Memory
and IO spaces.

The PCI attachment of the onboard re(4) uses PCI IO space in
preference to PCI Memory space for register accessses.  As IO space
was impossible to use, we had to avoid IO space.  This is now no
longer the case, so set up and enable IO space for PCI devices.

Also, map ROM BARs.
