Document USB2.0 phy bindings for RZ/G3E ("R9A09G047") SoC.

The RZ/G3E USB2.0 phy is functionally identical to the one found
on the RZ/V2H(P), so no driver changes are needed. The existing
"renesas,usb2-phy-r9a09g057" will be used as a fallback compatible for
this IP.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/32c6393bc89fd7f4b354def0028220a1916315e6.1764241212.git.tommaso.merciai.xr@bp.renesas.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
