pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()

In the Linux kernel, the following vulnerability has been resolved:

pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()

'new_map' is allocated using devm_* which takes care of freeing the
allocated data on device removal, call to

	.dt_free_map = pinconf_generic_dt_free_map

double frees the map as pinconf_generic_dt_free_map() calls
pinctrl_utils_free_map().

Fix this by using kcalloc() instead of auto-managed devm_kcalloc().
