of: Add function to find the same node in another tree

For our device tree fixups we have to find a node corresponding to
another node in another device tree. We used to use the full name
to match the nodes, but this falls apart when nodes get renamed
or for example a new bus hierarchy is introduced. To make this
more robust we create reproducible names from device nodes which
mostly depend on the address in MMIO space, the reg property and
as a last resort the name of the device node.
