Subject: drm: atmel-hlcdc: Fix vertical scaling

From: Jan Leupold <[email protected]>

commit d31ed3f05763644840c654a384eaefa94c097ba2 upstream.

The code is applying the same scaling for the X and Y components, thus making the scaling feature only functional when both components have the same scaling factor.

Do the s/_w/_h/ replacement where appropriate to fix vertical scaling.
