power: reset: at91-reset: introduce args member in at91_reset_data
Introduce args member in struct at91_reset_data. It stores the value that needs to be written in mode register so that the reboot actions to happen. With these changes samx7_restart() could be removed. Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
