i.MX arm64 device tree changes for v7.2 (part2)

- Revert the 32-bit non-prefetchable PCIe window from 3 GiB back to 1 GiB
 to prevent overlap between inbound DMA address space and low system RAM.
 Such overlap can cause DMA transactions to be routed to a BAR on the same
 host bridge instead of system memory.
