[POWERPC] 4xx: PCIe: Increase max busses per port to 64
Because of how big mapping the config space is (1M per bus), we limit how many busses we support for now. In the long run, we could replace that with something akin to kmap_atomic instead. This patch changes the limit from currently 16 to 64. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
