[PATCH v2] dts: imx: Enable USB support in imx8mm-phyboard-polis-rdk-u-boot.dtsi

[Lukasz Majewski]

The Phytec's imx8mm-phyboard-polis-rdk-u-boot.dtsi u-boot specific file
can be extended to support SDP gadget operation in SPL.

It is especially useful when one wants to flash the module via USB with
uuu program (USB ROM booting enabled).
