Renesas RZ/G2L SoC has USBPHY Control and USB2.0 PHY module. We need to
turn on both these phy modules before accessing host registers.

Apart from this, document the optional property dr_mode present on both
RZ/G2 and R-Car Gen3 SoCs.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:
./Documentation/devicetree/bindings/usb/generic-ehci.yaml:28:13: [warning] wrong indentation: expected 10 but found 12 (indentation)

dtschema/dtc warnings/errors:
\ndoc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1494982

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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.
