Chanho Park d2e9a13a38 usb: dwc3: set up burst size only superspeed mode
When connection is established non-ss mode, endpoint.maxburst is correctly set
to 0, this means that current code will set maxburst bitfield on DEPCFG's
parameter 0 to the highest possible value (0x0f) which is wrong.

Even though this hasn't caused any issues so far (HW seems to ignore that when
not running in SS mode) we want to make sure maxburst bitfield is only set to
anything other than zero if we're running on SuperSpeed mode. In order to
achieve that, let's check for gadget's operating speed before setting maxburst
bitfield when issuing DEPCFG command.
