usb: onboard-hub: Add support for Corechips SL6341 USB 2.0/3.0 hub controller

Corechips SL6341 is a 4-port USB 2.0 and 3.0 hub controller. It always
requires external 1V1 power and can optionally use external 3V3 power
(or alternatively it has a 5V->3V3 LDO built in to derive 3V3 power from
VBUS). It also exposes a reset pin.

Device tree bindings are merged for upstream release with Linux 7.1 as
commit bfcb86e58f3a ("dt-bindings: usb: Add Corechips SL6341 USB2.0/3.0
hub controller") [1]
