This is a partial revert of I67ace5c064b2b56d03732a78f334ea6b1b649608 which tries
to enable Sink CRC irrespective of the sink's CRC capability to workaround an
issue with a specific sinks which reports incorrect capability on first plugin.
But this causes some MST dongles to misbehave causing one or both outputs to
be blank.
