  arm64: dts: lx2160a-rev2: avoid 32-bit pcie window system ram overlap (2026-06-10 11:27:22 -0400)

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.
