AFAICS these are VLV specific. There are some other registers at
the same offset on other platforms.

I was going to say these are already in gen6, but looks like the offset
changed slightly in gen7. So the gen7 name is good here.

SNB already has UCGCTL3 and 4. So even the old name is a bit wrong.

These too already exist on gen6.
Same for GEN7_MISCCPCTL which should probably also be moved here and
renamed.

These three are already listed in my snb pm guide, so gen6. Also
should be inserted into the correct spot numerically.

This one isn't listed in the snb pm guide, but I get the impression
it should also say gen6 here.

Also seems like it should be gen6.
All the rest look fine.
