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.
