Subject: [PATCH 2/4] pinctrl: renesas: rzg2l: Fix missing of_node_put() call

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.

Fixes: c4c4637eb57f ("pinctrl: renesas: Add RZ/G2L pin and gpio controller driver")
