ARM: dts: renesas: Fix USB PHY device and child node names

make dtbs_check:

    usb-phy@e6590100: '#phy-cells' is a required property
	    From schema: dtschema/schemas/phy/phy-provider.yaml

The R-Car Gen2 USB PHY device nodes do not represent USB PHYs
theirselves, and thus do not have "#phy-cells" properties.  Fix the
warning by renaming them from "usb-phy" to "usb-phy-controller".
Rename their child nodes from "usb-channel" to "usb-phy", as these do
represent USB PHYs.
