Max upscale / downscale factors are constant between platforms. In
preparation to adding support for virtual planes and allocating SSPP
blocks on demand move max scaling factors out of the HW catalog and
handle them in the dpu_plane directly. If any of the scaling blocks gets
different limitations, this will have to be handled separately, after
the plane refactoring.
