[PATCH v2 2/5] ARM: at91/dts: add RTC nodes

[jhovold@gmail.com (Johan Hovold)]

Add RTC nodes for Atmel SOCs.

Use two different compatible properties to reflect the fact that the
RTC-peripherals are backup powered (VDDBU) and are thus not reset on
wake-up, user, watchdog or software reset on all SOCs but at91rm9200.
