dt-bindings: timer: Convert Allwinner A10 Timer to a schema

The older Allwinner SoCs have a Timer supported in Linux, with a matching
Device Tree binding.

While the original binding only mentions one interrupt, the timer actually
has 6 of them.

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

-Required properties:
-
-- compatible : should be one of the following:
-              "allwinner,sun4i-a10-timer"
-              "allwinner,suniv-f1c100s-timer"
-- reg : Specifies base physical address and size of the registers.
-- interrupts : The interrupt of the first timer
-- clocks: phandle to the source clock (usually a 24 MHz fixed clock)

-Example:
-
-timer {
-	compatible = "allwinner,sun4i-a10-timer";
-	reg = <0x01c20c00 0x400>;
-	interrupts = <22>;
-	clocks = <&osc>;
