[PATCH v7 9/9] arm64: dts: renesas: r9a08g046l48-smarc: Enable USB2.0 function support

[Biju]

From: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>

Switch ehci0 and ohci0 from dr_mode = "host" to "otg", and enable
the hsusb0 USB2.0 function controller node with dr_mode = "otg" and
status = "okay", so USB2.0 device/OTG mode is supported on the
RZ/G3L SMARC (r9a08g046l48) board.
