RZ/G2N board is pin compatible with RZ/G2M board. However on the SoC
side RZ/G2N uses DU3 where as RZ/G2M uses DU2 for the DPAD. In order to
reuse the common dtsi for both the boards, it is required to move du clock
properties from common dtsi to board specific dts.

According to the Renesas R-Car DU bindings documentation, the 'vsps'
property should be composed of a phandle to the VSP instance and the
index of the LIF channel assigned to the DU channel. Some SoC device
tree source files do not specify any LIF channel index, relying on the
driver defaulting to 0 if not specified.

Align all device tree files by specifying the LIF channel indices as
prescribed by the bindings documentation.
