fdt: Fix fdt_pci_dma_ranges handling of 64-bit ranges
If the size of a region equal to 4G it can't be represnted in a 32-bit
BAR so we should have marked that case as MEM64.
Additionally bump the number of inbound windows up to 4 to handle the
fact that Freescale PPCs that have an implicit window for CCSRBAR.
