ARM: at91: pm: Add sama5d2 backup mode
The sama5d2 has a mode were it is possible to cut power to the SoC while keeping the RAM in self refresh. Resuming from that mode needs support in the firmware/bootloader. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Acked-by: Wenyou Yang <wenyou.yang@atmel.com>
