facetimehd: set device_caps in video_device

Browse Source 
In kernel 5.4 I otherwise get this warning

WARNING: CPU: 1 PID: 451 at drivers/media/v4l2-core/v4l2-dev.c:863 __video_register_device+0x64b/0xe90 [videodev]
The code there is:

        /* the device_caps field MUST be set for all but subdevs */
        if (WARN_ON(type != VFL_TYPE_SUBDEV && !vdev->device_caps))
