documentation: add a section on devicetree refs

There is no existing documentation on how `device ref` and aliases work
in the devicetree, and the behavior around devices not being in the same
location is difficult to discern as well as somewhat unexpected.

This should help prevent confusion leading to bugs such as the one fixed
by https://review.coreboot.org/c/coreboot/+/57298
