mpc8641: Make PCI and RIO mutually exclusive, fix non-PCI build
You can't actually have both, and with some coming changes to change the memory map for the board and support 36-bit physical, we need the extra BAT that is being consumed by having both. I also make non-PCI configs build cleanly, for the sake of sanity. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
