[ 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.
