powerpc/fsl-pci: Limit ZONE_DMA32 to 2GiB on 64-bit platforms FSL PCI cannot directly address the whole lower 4 GiB due to conflicts with PCICSRBAR and outbound windows. By the time max_direct_dma_addr is set to the precise limit, it will be too late to alter the zone limits, but we should always have at least 2 GiB mapped (unless RAM is smaller than that).
