pinctrl: cherryview: add handlers for pin_config_group_get/set
Pin config get/set handlers for pin groups were previously not implemented by this driver. The pin_config_group_set is particularly useful for applying a common config setting to all pins in a specified group with a single call, without the caller needing to reference each individual pin by name.
