usb: misc: onboard-hub: add support for Cypress HX3 USB 3.0 family



The HX3 comes in different variants (up to 4 USB 3.0 ports; multi-TT),
e.g. CYUSB330x/CYUSB331x/CYUSB332x/CYUSB230x. 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.
