libcamera: pipeline: uvcvideo: Generate unique camera names

Generate camera names that are unique and persistent between system resets. The name is constructed from the USB device information as well as the USB controller on the host. Before this change example of camera names: Venus USB2.0 Camera: Venus USB2 Logitech Webcam C930e After this change the same cameras are: \_SB_.PCI0.RP05.PXSX-2.1.1:1.0-0ac8:3420 \_SB_.PCI0.RP05.PXSX-2.4:1.0-046d:0843 On OF-based system: /base/soc/usb@7e980000/usb-port@1-1.2:1.0-0ac8:3420 Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
