media: subdev: Don't report V4L2_SUBDEV_CAP_STREAMS when the streams API is disabled
Since the stream API is still experimental it is currently locked away
behind the internal, default disabled, v4l2_subdev_enable_streams_api flag.
Advertising V4L2_SUBDEV_CAP_STREAMS when the streams API is disabled
confuses userspace. E.g. it causes the following libcamera error:
ERROR SimplePipeline simple.cpp:1497 Failed to reset routes for
/dev/v4l-subdev1: Inappropriate ioctl for device
Don't report V4L2_SUBDEV_CAP_STREAMS when the streams API is disabled
to avoid problems like this.
