[PATCH v3 21/23] drm/omap: venc: Fixup video mode in .check_timings() operation

The VENC encoder modifies the requested video mode to match the NTSC or
PAL timings (or reject the video mode completely) in the .set_timings()
operation. This should be performed in the .check_timings() operation
instead. Move the fixup.
