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.
