This patch enables skylake display scalers in atomic framework. Skylake scalers are sharable within a pipe and can be used as a panel fitter or plane scaler. Two scalers cannot be ganged to a single plane to get higher scale factor but simultaneous use of one as plane scaler and one scaler as panel fitter is allowed. Reformatted previous patch series into smaller patches and addressed previous feedback inputs. Performed some initial testing and more testing is in works. Testing is done applying these patches on top of Ander's v2 atomic crtc patches. As several atomic crtc is in flight, will revisit scalers and perform any additional testing after atomic crtc is in place.
