[RFC PATCH 5/7] pinctrl: at91-pio4: allow the gpiolib to set pin configuration

[Ludovic Desroches <ludovic.desroches@microchip.com>]

Use gpiochip_generic_config to allow the gpiolib to set pin
configuration. Since it relies on .pin_config_set(), add it too.
For this controller, one pin is on group so we can use
atmel_conf_pin_config_group_set() function.
