power: reset: at91-reset: introduce struct at91_reset_data
Introduce struct at91_reset_data to be able to provide per SoC data. At the moment this being only notifier callback. Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
