Don't grow the examples.

It is enough to have one example to validate the schema and show how the
binding is used. If schema covers multiple combinations of devices and
their properties, then more than one example seems reasonable. This is
not the case. All of this is redundant... and redundant information is
not good because as this commit shows it leads to something which people
think is not correct and they find bugs. So just drop the redundant
information.

Keep only one, correct example.

Best regards,
