[PATCH] usb: onboard-hub: Add support for CoreChips SL6341

[Alexey Charkov]

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 queued up for upstream release with Linux 7.1
