Add missing of_node_put() and put_device() calls to release references.

The function calls of_parse_phandle() and of_find_device_by_node() but fails to release the references. Both functions' documentation mentions that the returned references must be dropped after use.

Found through static analysis by reviewing the documentation and cross-checking their usage patterns.
