of: Migrate of_find_node_by_name() users to for_each_node_by_name()
There are a bunch of users open coding the for_each_node_by_name() by calling of_find_node_by_name() directly instead of using the macro. This is getting in the way of some cleanups, and the possibility of removing of_find_node_by_name() entirely. Clean it up so that all the users are consistent.
