The BCM2835 SoC contains a DWC2 USB controller. Add this to the DT. Set up the pin controller to fully enable the USB controller on the Raspberry Pi. The GPIO setup works because the default output value for GPIO 6 (LAN_RUN/n_reset) just happens to be 1, which enables the USB/LAN chip. Note that you'll need a U-Boot which enables power to the USB controller; search for U-Boot patch "ARM: rpi_b: power on SDHCI and USB HW modules".
