Subject: [PATCH v3 4/9] usb: misc: onboard_usb_hub: add Genesys Logic GL852G hub support

Genesys Logic GL852G is a 4-port USB 2.0 STT 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.
