This patch series introduces support for the USB on the SpacemiT K1 SoC,
including DWC3 host controller, PCIe/USB3.0 combo PHY and the USB2.0 PHY.
The implementation has been tested on the Milk-V Jupiter and BananaPi-f3.

USB3.0 PHY for usb2 is shared with PCIe port A, meaning that only one of
these interfaces (PCIe or USB3.0) can be active at a given time.
