[ Upstream commit f2fc9ff28d1c9bef7760516feadd38164044caae ] In preparation for USB 3.2 dual-lane support, add sublink speed attribute macros and enum usb_ssp_rate. A USB device that operates in SuperSpeed Plus may operate at different speed and lane count. These additional macros and enum values help specifying that.
