[PATCH 06/16] dt-bindings: reset: renesas,rzg2l-usbphy-ctrl: Document RZ/G3S SoC

From: Claudiu Beznea <claudiu.beznea.uj at bp.renesas.com>

Document the Renesas RZ/G3S USB PHY Control IP. This is similar with the
one found on the RZ/G2L SoC the exception being that the SYSC USB specific
signal need to be configured before accessing the USB area. This is
done though a reset signal.
