arm64: dts: lx2160a-rev2: avoid 32-bit pcie window system ram overlap

A 3GB non-prefetchable PCIe bus window can overlap with inbound DMA
addresses for low system RAM, so DMA transactions may be routed to a BAR
on the same host bridge instead of memory.

Change the 32-bit non-prefetchable PCIe window back from 3GB to 1GB on all
controllers, avoiding that overlap while keeping the added 64-bit
prefetchable region.

This partially reverts commit 9ed301397090 ("arm64: dts: lx2160a-rev2:
extend 32-bit and add 64-bit pci regions").
