This series adds RTT support for SAM9X60.

Changes in v2:
- use "atmel,at91sam9260-rtt" as fallback for compatible
- in patch 1 keep only the addition of sam9x60_aic_irq_fixup
- get rid of patches 2/5 from v1
- squash patches 4/5, 5/5 from v1
- change commit title for patch "rtc: at91sam9: add microchip,sam9x60-rtt"
  from v1 into "dt-bindings: rtc: add microchip,sam9x60-rtt" and
  place it before device tree patch
