[PATCH v2 1/2] sata_rcar: Add clocks to sata_rcar bindings

[Geert Uytterhoeven <geert+renesas@glider.be>]

From: Valentine Barshak <valentine.barshak@cogentembedded.com>

Now that the clocks are available in the R-Car Gen2 DT,
add clocks property description to the sata_rcar bindings.
The clocks have been tested on r8a7791 so we use that
as an example of the R-Car SATA node.
