Added a property to enable user space to set aspect ratio. This patch contains declaration of the property and code to create the property.

Documentation update is missing. Also for such patch series I recommend to post the entire patch series to dri-devel and intel-gfx. Otherwise people on dri-devel don't see how the new code is used and so can't really review it properly. -Daniel
