dt-bindings: rtc: Convert Allwinner A31 RTC to a schema

The newer Allwinner SoCs have an embedded RTC supported in Linux, with a
matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

-RTC controller for the Allwinner A31
-
-Required properties:
-- compatible	: Should be one of the following combinations:
-		    - "allwinner,sun6i-a31-rtc"
-		    - "allwinner,sun8i-a23-rtc"
-		    - "allwinner,sun8i-h3-rtc"
-		    - "allwinner,sun8i-r40-rtc", "allwinner,sun8i-h3-rtc"
-		    - "allwinner,sun8i-v3-rtc"
-		    - "allwinner,sun50i-a64-rtc", "allwinner,sun8i-h3-rtc"
-		    - "allwinner,sun50i-h5-rtc"
-
-		  Where there are two or more compatible strings, this
-		  denotes the hardware covered by the most specific one
-		  is backward-compatible with the latter ones, and the
-		  implementation for the latter ones can be used, albeit
-		  with reduced functionality.
-
-- reg		: physical base address of the controller and length of
-		  memory mapped region.
-- interrupts	: IRQ lines for the RTC alarm 0 and alarm 1, in that order.
-
-Required properties for new device trees
-- clocks	: phandle to the 32kHz external oscillator
-- clock-output-names : names of up to three clock outputs. See below.
-- #clock-cells  : must be equal to 1.
-
-The RTC provides the following clocks at the given indices:
-- 0: LOSC
-- 1: LOSC external output, known as X32KFOUT in the datasheet.
-     This clock is not available on the A31 and is deprecated for old
-     device trees still using the "allwinner,sun6i-a31-rtc" compatible.
-- 2: InternalOSC, or internal RC oscillator (A64/H3/H5 only)
-
-Example:
-
-rtc: rtc@1f00000 {
-	compatible = "allwinner,sun6i-a31-rtc";
-	reg = <0x01f00000 0x400>;
-	interrupts = <0 40 4>, <0 41 4>;
-	clock-output-names = "osc32k";
-	clocks = <&ext_osc32k>;
-	#clock-cells = <1>;
-};
