arm64: tegra: Add reserved-memory node for P2180

Browse Source 
The Tegra210 L4T bootloader RAM training will corrupt the in-RAM kernel
DT if no reserved-memory node exists. This prevents said bootloader from
being able to boot a kernel without this node, unless a chainloaded
bootloader loads the DT. Add the node to eliminate the requirement for
extra boot stages.
