dt-bindings: documentation: add clock bindings information for Stratix10

Document that Stratix10 clock bindings, and add the clock header file. The
clock header is an enumeration of all the different clocks on the Stratix10
platform.

+Device Tree Clock bindings for Intel's SoCFPGA Stratix10 platform
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be
+	"intel,stratix10-clkmgr"
+
+- reg : shall be the control register offset from CLOCK_MANAGER's base for the clock.
+
+- #clock-cells : from common clock binding, shall be set to 1.
+
+Example:
+	clkmgr: clock-controller@ffd10000 {
+		compatible = "intel,stratix10-clkmgr";
+		reg = <0xffd10000 0x1000>;
+		#clock-cells = <1>;
+	};
