usb: gadget: Introduce udc_set_ssp_rate() for SSP
A SuperSpeed Plus device may operate at different speed and lane count
(i.e. gen2x2, gen1x2, or gen2x1). Introduce gadget ops
udc_set_ssp_rate() to set the desire corresponding usb_ssp_rate for
SuperSpeed Plus capable devices.
If the USB device supports different speeds at SuperSpeed Plus, set the
device to operate with the maximum number of lanes and speed.
