[PATCH v2 3/3] power: reset: at91-reset: add support for sam9x60 SoC

Add support for additional reset causes and the proper compatibility
string for sam9x60 SoC. The restart function is the same as the samx7.

Sebastian,
I add your Acked-by tag here but as I would like that you take the 3 patches on
your tree now, I let you modify it on your side. I'm expecting Alexandre or
Ludovic to have a look as well.

Best regards,
  Nicolas
