drm: clarify scaling property names
Now that we're using the scaling property in the Intel driver I noticed that the names were a bit confusing. I've corrected them according to our discussion on IRC and the mailing list, though I've left out potential new additions for a new scaling property with an integer (or two) for the scaling factor. None of the drivers implement that today, but if someone wants to do it, I think it could be done with the addition of a single new type and a new property to describe the scaling factor in the X and Y directions.
