rtc: digicolor: document device tree binding
Add a device tree binding documentation to the Real Time Clock hardware block on the Conexant CX92755 SoC. The CX92755 is from the Digicolor SoCs series. Other SoCs in that series may share the same hardware block.

+Conexant Digicolor Real Time Clock controller
+
+This binding currently supports the CX92755 SoC.
+
+Required properties:
+- compatible: should be "cnxt,cx92755-rtc"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: rtc alarm interrupt
+
+Example:
+
+ rtc@f0000c30 {
+ compatible = "cnxt,cx92755-rtc";
+ reg = <0xf0000c30 0x18>;
+ interrupts = <25>;
+ };
