drm/i915/cnl: Also need power well sanitize. 

The workaround added in
commit c6782b76d3 ("drm/i915/gen9: Reset secondary power well
equests left on by DMC/KVMR")
needs to be applied on Cannonlake as well.

So let's assume any platform using this power well setup
will also need and let's just go ahead and remove if condition.
