drm/rockchip: vop2: Add mode valid callback for crtc

Browse Source 
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.
