dt-bindings: timer: Convert Allwinner A13 HSTimer to a schema

The newer Allwinner SoCs have a High Speed Timer 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.

-Allwinner SoCs High Speed Timer Controller
-
-Required properties:
-
-- compatible :	should be "allwinner,sun5i-a13-hstimer" or
-		"allwinner,sun7i-a20-hstimer"
-- reg : Specifies base physical address and size of the registers.
-- interrupts :	The interrupts of these timers (2 for the sun5i IP, 4 for the sun7i
-		one)
-- clocks: phandle to the source clock (usually the AHB clock)
-
-Optional properties:
-- resets: phandle to a reset controller asserting the timer
-
-Example:
-
-timer@1c60000 {
-	compatible = "allwinner,sun7i-a20-hstimer";

-	clocks = <&ahb1_gates 19>;
-	resets = <&ahb1rst 19>;
