pinctrl: berlin: fix the dt_free_map function
The berlin_pinctrl_dt_free_map function tries to free memory allocated and handled by the of subsystem. This is wrong and already handled by pinctrl_dt_free_maps() which calls of_node_put(). This patch fixes the Berlin pinctrl way of freeing its maps, avoiding a kernel BUG(), by using the common pinctrl_utils_dt_free_map function instead.
