Subject: [PATCH] dt-bindings: clock: adi,axi-clkgen: convert old binding to yaml format

This change converts the old binding for the AXI clkgen driver to a yaml
format.

As maintainers, added:
 - Lars-Peter Clausen <lars@...afoo.de> - as original author of driver &
   binding
 - Michael Hennerich <michael.hennerich@...log.com> - as supporter of
   Analog Devices drivers

-Binding for the axi-clkgen clock generator
-
-This binding uses the common clock binding[1].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : shall be "adi,axi-clkgen-1.00.a" or "adi,axi-clkgen-2.00.a".
-- #clock-cells : from common clock binding; Should always be set to 0.
-- reg : Address and length of the axi-clkgen register set.
-- clocks : Phandle and clock specifier for the parent clock(s). This must
-	either reference one clock if only the first clock input is connected or two
-	if both clock inputs are connected. For the later case the clock connected
-	to the first input must be specified first.
-
-Optional properties:
-- clock-output-names : From common clock binding.

-Example:
-	clock@...00000 {
-		compatible = "adi,axi-clkgen";
-		#clock-cells = <0>;
-		reg = <0xff000000 0x1000>;
-		clocks = <&osc 1>;
