arm: dts: k3-am625-sk: Add support for USB instances brought out on the board 

The two instance of USB IP in AM62 SoC are brought out on the SK board. The
zeroth instance is brought out through a USB TYPE C port and the first
instance through a USB TYPE A port. As role switching is supported in
U-Boot and dfu support is required, fix the role of zeroth instance to
peripheral in the U-Boot dts file.
