Subject: [PATCH v3 3/6] usb: misc: onboard_usb_dev: Add Bison Electronics
 Inc. Integrated Camera

From: Jens Glathe <jens.glathe@...schoolsolutions.biz>

The Camera is built into the Thinkbook 16 G7 QOY and directly attached on the
usb_2 controller (dwc3 USB2 only). It has a separate power supply that needs
to be controlled for PM.

Add the support for this device for the power supply.
