of: add optional options parameter to of_find_node_by_path()
Update of_find_node_by_path(): 1) Rename function to of_find_node_opts_by_path(), adding an optional pointer argument. Provide a static inline wrapper version of of_find_node_by_path() which calls the new function with NULL as the optional argument. 2) Ignore any part of the path beyond and including the ':' separator. 3) Set the new provided pointer argument to the beginning of the string following the ':' separator. 4: Add tests.
