dt-bindings: arm: hisilicon,cpuctrl: Merge "hisilicon,hix5hd2-clock" into parent binding

The "hisilicon,hix5hd2-clock" is simple enough to just add it into its
parent node binding, "hisilicon,cpuctrl".

This fixes a warning that "hisilicon,hix5hd2-clock" is missing a schema.

-* Hisilicon Hix5hd2 Clock Controller
-
-The hix5hd2 clock controller generates and supplies clock to various
-controllers within the hix5hd2 SoC.
-
-Required Properties:
-
-- compatible: should be "hisilicon,hix5hd2-clock"
-- reg: Address and length of the register set
-- #clock-cells: Should be <1>
-
-Each clock is assigned an identifier and client nodes use this identifier
-to specify the clock which they consume.
-
-All these identifier could be found in <dt-bindings/clock/hix5hd2-clock.h>.
-
-Examples:
-	clock: clock@f8a22000 {
-		compatible = "hisilicon,hix5hd2-clock";
-		reg = <0xf8a22000 0x1000>;
-		#clock-cells = <1>;
-	};
-
-	uart0: uart@f8b00000 {
-		compatible = "arm,pl011", "arm,primecell";
-		reg = <0xf8b00000 0x1000>;
-		interrupts = <0 49 4>;
-		clocks = <&clock HIX5HD2_FIXED_83M>;
-		clock-names = "apb_pclk";
-	};
