The max speed was always being set to USB_SUPER_SPEED
even when the phy was only capable of HIGH_SPEED. This
uses the value set for the phy to set the max for the
gadget. It resolves an issue with Window PCs where they
report that using a USB3.0 port would result in better
performance even when connecting through a 3.0 port.
