[PATCH 3/3] pinctrl: bcm: Use pinconf_generic_dt_free_map in brcmstb

[Wang Xiaolei <wangxiaolei01@kaihong.com>]

Replace the hand-written dt_free_map callback with the generic
pinconf_generic_dt_free_map() helper, which wraps
pinctrl_utils_free_map(). This drops the duplicated free loop and
pairs the callback with the pinconf_generic_dt_node_to_map_all()
already used for dt_node_to_map.

The driver already selects GENERIC_PINCONF, so no Kconfig change is
needed.
