Add the 'ssp_descriptors' parameter to the usb_assign_descriptors()
function. This allows a function driver to add descriptors for
SuperSpeedPlus speeds if it supports it.
Also update all uses of this function in the gadget subsystem so that
they pass NULL for the ssp_descriptors parameters.

The SuperspeedPlus Device Capability Descriptor has a variable size

This patch adds a macro to calculate that size. The macro takes one
argument, the Sublink Speed Attribute Count (SSAC) as reported by the
