It operates with two different power supplies: 1V2 and 3V3. Add the support for this hub, for controlling the reset pin and the power supplies. Reset time is extracted from data sheet, page 24: "The RESETN pin can be tied to VDD_IO through an external resistor and to ground (GND) through an external capacitor (minimum 5 ms time constant)." V_IH min is given at 0.7 * 3V3 (page 34), therefore use 10ms. Also add USB PIDs for the USB 2.0 and USB 3.0 root hub.
