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.

Nit: usually these are sorted by part number, so the RZ/G3S section
should be last.
