[PATCH 3/4] dt-bindings: rtc: digicolor-rtc: convert to dtschema

[Javier Carrasco]

Convert existing binding to dtschema to support validation.

The binding has been renamed to match its compatible. Apart from that,
it is a direct conversion with no additions.

-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>;
