Add support for TechnoTrend TT-budget S2-4200 Twin DVB-S2 tuner. The

- Add a check for the case that both the cropcap and g_selection ops
  are NULL. This shouldn't happen, but I feel happier if the code
  guards against this.

- If g_selection exists, then ignore ENOTTY and ENOIOCTLCMD error
  codes from cropcap. Just assume square pixelaspect ratio in that
  case. This situation can happen if the bridge driver's cropcap op
  calls the corresponding subdev's op. So the cropcap ioctl is set,
  but it might return ENOIOCTLCMD anyway. In the past this would
  just return an error which is wrong.

- Call cropcap first and let g_selection overwrite the bounds and
  defrect. This safeguards against subdev cropcap implementations
  that set those rectangles as well. What g_selection returns has
  priority over what such cropcap implementations return.

Both of these drivers can return NOTIFY_BAD, but this terminates
processing other callbacks that were registered later on the chain.
Since the driver did nothing to log the error it seems wrong to prevent
other interested parties from seeing it. E.g. neither of them had even
bothered to check the type of the error to see if it was a memory error
before the return NOTIFY_BAD.

According to the V4L2 API, the VIDIOC_STREAMON ioctl should return EPIPE
if there is a format mismatch in the pipeline configuration.

As the .vidioc_streamon in the v4l2_ioctl_ops usually forwards the error
caused by the v4l2_subdev_link_validate_default (if it is in use), it
should return -EPIPE when it detect the mismatch.

When an entity is connected to a non enabled link,
media_entity_pipeline_start should return -ENOLINK, as the link does not
exist.
