drm/rockchip: vop: Allow 4096px width scaling

There is no reason to limit VOP scaling to 3840px width, the limit of
RK3288, when there are newer VOP versions that support 4096px width.

Change to enforce a maximum of 4096px width plane scaling, the maximum
supported output width of the VOP versions supported by this driver.
