Subject: [PATCH v2 6/9] dt-bindings: rtc: Convert sa1100-rtc to json-schema

Convert the sa1100-rtc binding to DT schema format using json-schema.
While add that, add clocks and resets that are actually used.

Signed-off-by: Lubomir Rintel <lkundrak@...sk>

Changes since v1:
- Remove interrupts/maxItems
- Mention clocks and resets in the patch description
- Add default GPL-2.0-only license tag
- Fill in maintainers from MAINTAINERS file

-* Marvell Real Time Clock controller
-
-Required properties:
-- compatible: should be "mrvl,sa1100-rtc"
-- reg: physical base address of the controller and length of memory mapped
-  region.
-- interrupts: Should be two. The first interrupt number is the rtc alarm
-  interrupt and the second interrupt number is the rtc hz interrupt.
-- interrupt-names: Assign name of irq resource.
-
-Example:
-	rtc: rtc@...10000 {
-		compatible = "mrvl,mmp-rtc";
-		reg = <0xd4010000 0x1000>;
-		interrupts = <5>, <6>;
-		interrupt-names = "rtc 1Hz", "rtc alarm";
-	};
