drm/rockchip: vop2: Add mode valid callback for crtc
The different Video Ports support different maximum resolutions.
Reject resolutions that are not supported by a specific VP.
Only the output width is checked because the hardware itself does
not have a hard output height limit.
Filter the mode that can't output by the VP/crtc.
