gpio: rcar: Fix missing of_node_put() call

Browse Source 
[ Upstream commit 391b41f983 ]

of_parse_phandle_with_fixed_args() requires its caller to
call into of_node_put() on the node pointer from the output
structure, but such a call is currently missing.

Call into of_node_put() to rectify that.
