pinctrl: starfive: Serialize adding groups and functions

The pinctrl dt_node_to_map method may be called in parallel which leads
us to call pinconf_generic_add_group and pinconf_generic_add_function
in parallel. This is not supported though and leads to errors, so add a
mutex to serialize these calls.
