We've had a bunch of nodes (like the PSCI nodes) created in the same way for quite some time already without causing any issues.

Using skeleton.dtsi will create a memory node that will generate a warning in DTC. However, that node will be created by the bootloader, so we can just remove it entirely in order to remove that warning.
