[PATCH 03/13] drm/rockchip: vop: Allow 4096px width scaling

From: Alex Bee <knaerzche@gmail.com>

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.

Fixes: 4c156c21c794 ("drm/rockchip: vop: support plane scale")
