Fix config warning: warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies (USB_SUPPORT && USB_ARCH_HAS_HCD) and build error: ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined! by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.

This is a KMS driver for the USB displaylink video adapters.

Say M/Y to add support for these devices via drm/kms interfaces.
