ARM: dts: tegra: Increase prefetchable PCI memory space
Instead of evenly splitting the 512 MiB area between prefetchable and non-prefetchable memory spaces, increase the prefetchable memory space to 384 MiB while at the same time decreasing the non-prefetchable memory space to 128 MiB. This is a more useful default as most PCIe devices require more prefetchable than non-prefetchable memory.
