pinctrl: sunxi: implement pin_config_set

Browse Source 
The sunxi pinctrl only implements the pin_config_group_set callback at the
moment, whereas the gpiochip_generic_config function relies on
pin_config_set. Rework the functions a little to support pin_config_set,
and rely on it for pin_config_group_set.
