This makes no sense to begin with. You do not need a new compatible just
for clock ID change (processor ID has nothing to do with vtm node).

This approach is just plain wrong. AVS support has been done in the past
(class 3,2,1.5 and 0) and bindings have been mature for more that a
decade for the same.

So NAK for this patch
