drm/rockchip: vop: Allow 4096px width scaling

[ Upstream commit 0ef968d91a20b5da581839f093f98f7a03a804f7 ]

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.
