Subject: [PATCH v2 3/6] usb: misc: onboard_usb_hub: add Genesys Logic GL850G hub support

Genesys Logic GL850G is a 4-port USB 2.0 STT hub that has a reset pin to
toggle and a 3.3V core supply exported (although an integrated LDO is
available for powering it with 5V).

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