Add a basic driver for the DesignWare USB3 host controller as found in the Lichee Pi 4A. This driver covers only the DesignWare host controller hardware. On the Lichee Pi 4A, this is sufficient to get the single USB root hub port (exposed internally via the SODIMM connector) up and running. The driver does not yet handle the various GPIOs that control power and signal routing for the Lichee Pi 4A's onboard VL817 USB hub and the four physical USB-A ports. This therefore leaves the USB hub and the USB-A ports unpowered, and the USB2 root hub port routed to the physical USB-C port. Devices plugged in to the USB-A ports will not be powered up, and a device plugged in to the USB-C port will enumerate as a USB2 device. Signed-off-by: Michael Brown <mcb30@ipxe.org>
