Yeah, while cursors themselves don't change between non-DDI and DDI
platforms, the reason for this stuff is the fact that that we use
the pipe csc for HDMI color range mangling on DDI platforms, since
they no longer have any other pipe/port controls for it.

So makese sense to check for DDI here too I think:
