Redundant. You've already done the link_configuration |= above in the
common code. You can drop the second if chunk altogether.
In related news, the corresponding section for this in TRANS_DP_CTL
setup appears to turn on enhanced framing unconditionally. This is
probably not a big deal, I don't think I've ever seen a display not
support it, but.
