media: Documentation: Update {enable,disable}_streams documentation
Document the expected {enable,disable}_streams callback behaviour for
drivers that are stream-unaware i.e. don't specify the
V4L2_SUBDEV_CAP_STREAMS sub-device capability flag. In this specific case,
the mask argument can be ignored.
