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.
