usb: misc: onboard_usb_hub: add VIA LAB VL817 hub support

VIA LAB VL817 is a 4-port USB 3.1 hub and USB 2.0 root 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.

Add USB device id's for USB 2.0 and USB 3.0 root hub.
