[PATCH v1 10/11] usb: misc: onboard_usb_hub: add VIA LAB VL817Q7 hub support

VIA LAB VL817Q7 is a 4-port USB 3.1 hub that has a reset pin to
toggle and a 5.0V core supply exported though an integrated LDO is
available for powering it.

Add the support for this hub, for controlling the reset pin and the core
power supply.
