dt-bindings: clk: imx: Add fsl,scu-clk yaml file

In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'clock' child node of the SCU main node.

-This binding uses the common clock binding[1].

-Required properties:
-- compatible:		Should be one of:
-			  "fsl,imx8dxl-clk"
-			  "fsl,imx8qm-clk"
-			  "fsl,imx8qxp-clk"
-			followed by "fsl,scu-clk"
-- #clock-cells:		Should be 2.
-			Contains the Resource and Clock ID value.
-- clocks:		List of clock specifiers, must contain an entry for
-			each required entry in clock-names
-- clock-names:		Should include entries "xtal_32KHz", "xtal_24MHz"
-
-The clock consumer should specify the desired clock by having the clock
-ID in its "clocks" phandle cell.
