pinctrl: at91-pio4: Add persist state case in config
Adding persist state case to atmel_conf_pin_config_group_set() function. After adding configuration support for userspace gpiod api, there was an extra flag PIN_CONFIG_PERSIST_STATE that was not passed in before. Based on other drivers like TI drivers, added a switch case and return ENOTSUPP in that case.
