-RTC controller for the Armada 38x, 7K and 8K SoCs

-Required properties:
-- compatible : Should be one of the following:
-	"marvell,armada-380-rtc" for Armada 38x SoC
-	"marvell,armada-8k-rtc" for Aramda 7K/8K SoCs
-- reg: a list of base address and size pairs, one for each entry in
-  reg-names
-- reg names: should contain:
-  * "rtc" for the RTC registers
-  * "rtc-soc" for the SoC related registers and among them the one
-    related to the interrupt.
-- interrupts: IRQ line for the RTC.

-Example:
-
-rtc@...00 {

-	reg = <0xa3800 0x20>, <0x184a0 0x0c>;

-	interrupts = <GIC_SPI 21 IRQ_TYPE_LEVEL_HIGH>;
