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.

* 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@d4010000 {
compatible = "mrvl,mmp-rtc";
reg = <0xd4010000 0x1000>;
interrupts = <5>, <6>;
interrupt-names = "rtc 1Hz", "rtc alarm";
};
