The ACPI has ways to annotate the location of a USB device. Wire that
annotation to a v4l2 control.

To support all possible devices, add a way to annotate USB devices on DT
as well. The original binding discussion happened here:
https://lore.kernel.org/linux-devicetree/20241212-usb-orientation-v1-1-0b69adf05f37@chromium.org/

This set includes a couple of patches that are "under review" but
conflict.
