* Find a node from a device tree path, relative to a parent node. * * @param parent The node from which to start the relative path lookup. * @param path An array of path component strings that will be looked * up in order to find the node. Must be terminated with * a NULL pointer. Example: {'firmware', 'coreboot', NULL} * @param addrcp Pointer that will be updated with any #address-cell

 * @return		The found/created node, or NULL.
