drm/rockchip: vop: limit maximum resolution to hardware capabilities

The different VOP variants support different maximum resolutions. Reject
resolutions that are not supported by a specific variant.

This hasn't been a problem in the upstream driver so far as 1920x1080
has been the maximum resolution supported by the HDMI driver and that
resolution is supported by all VOP variants. Now with higher resolutions
supported in the HDMI driver we have to limit the resolutions to the
ones supported by the VOP.

The actual maximum resolutions are taken from the Rockchip downstream
Kernel.

[dropped the vdisplay > height check after talking to Sascha, as according to
 the vendor code "Actually vop hardware has no output height limit"
 (from vendor commit "drm/rockchip: vop: get rid of max_output.height check")
 and the height-check broke the px30-minievb display]
