[PATCH 5/8] dt-bindings: usb: usb-device: Add orientation

[Ricardo Ribalda]

For some devices, such as cameras, the OS needs to know where they are
mounted.

ACPI has a property for this purpose, which is parsed by
acpi_get_physical_device_location():
https://uefi.org/htmlspecs/ACPI_Spec_6_4_html/06_Device_Configuration/Device_Configuration.html#pld-physical-location-of-device

In DT we have similar property for video-interface-devices called
orientation:
Documentation/devicetree/bindings/media/video-interface-devices.yaml

Add a new property orientation for usb-devices that matches the already
existing orientation property of video-interface-devices.
