From: Abel Vesa <[e-mail]>

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.

+description: i.MX SCU Client Device Node
+  Client nodes are maintained as children of the relevant IMX-SCU device node.
+  This binding uses the common clock binding.
+  (Documentation/devicetree/bindings/clock/clock-bindings.txt)
+  The clock consumer should specify the desired clock by having the clock
+  ID in its "clocks" phandle cell.
+  See the full list of clock IDs from
+  include/dt-bindings/clock/imx8qxp-clock.h
