Subject: [PATCH] dt-bindings: clock: renesas: Make example 'clocks' parsable

'clocks' in the example is not parsable with the 0 phandle value
because the number of #clock-cells is unknown in the previous entry.
Solve this by adding the clock provider node. Only 'cpg_clocks' is
needed as the examples are built with fixups which can be used to
identify phandles.

This is in preparation to support schema validation on .dtb files.
