pinctrl: imx: scmi: replace custom dt_free_map with pinctrl_utils_free_map

pinctrl_scmi_imx_dt_node_to_map() kmemdup_array()s the pinctrl configs
of every pin into map[i].data.configs.configs, but the driver's own
pinctrl_scmi_imx_dt_free_map() only frees the map array itself. The
pinctrl core releases maps through pinctrl_dt_free_maps(), which calls
dt_free_map(); the duplicated configs are therefore never freed and leak
every time the DT node is parsed, e.g. on each (deferred) probe attempt.

Replace the custom dt_free_map with the core helper
pinctrl_utils_free_map(), which frees the configs of each
PIN_MAP_TYPE_CONFIGS_* map before freeing the map itself. Its
signature matches pinctrl_ops.dt_free_map(), so the driver-specific
implementation can be dropped entirely.

Detected with kmemleak on an i.MX95 board (FRDM-IMX95).
