USB: composite: Advertise USB version as 0x200 if max speed is HS
Currently driver is advertising as USB device as 0x210 even if
maximum speed is limited to high speed mode. This is causing throughput
degradation for RNDIS with host machines that enables USB2 LPM. Hence
disable USB2 LPM for device having maximum speed limited to high speed
mode by advertizing as 0x200.
