usb: misc: onboard_usb_hub: add Genesys Logic GL850G hub support

[ Upstream commit 9bae996ffa28ac03b6d95382a2a082eb219e745a ]

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.
