usb: define HCD_USB32 speed option for hosts that support USB 3.2 dual-lane
Hosts that support USB 3.2 Enhaned SuperSpeed can set their hcd speed
to HCD_USB32 to let usb core and host drivers know that the controller
supports new USB 3.2 dual-lane features.
make sure usb core handle HCD_USB32 hosts correctly, for now similar
to HCD_USB32.
