If no other USB HCDs are selected when compiling a small pure virutal machine, the Xen HCD driver cannot be built. Fix it by traversing down host/ if CONFIG_USB_XEN_HCD is selected.

To reduce the patch size a little bit, the header file gadget.h was intentionally added as separate patch. The Cadence USBSSP DRD Controller is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI)configurations. The current driver has been validated with FPGA platform. We have support for PCIe bus, which is used on FPGA prototyping. The host side of USBSS DRD controller is compliant with XHCI. The architecture for device side is almost the same as for host side, and most of the XHCI specification can be used to understand how this controller operates.

Get rid of its USB driver too, which is now unused.

The biggest change here is the addition of the Cadence USB3 DRD Driver. All other changes are small, non-critical fixes or smaller new features like the improvement to BESL handling in dwc3.

In order to properly do this, we need to load the common code before the usb core code, when everything is linked into the kernel, so reorder the link order of the code. Also as the usb common code has the possibility of the led trigger logic to be merged into it, handle the build option properly by only having one module init/exit function and have the common code initialize the led trigger if needed.
