[PATCH v2 26/49] drm/omap: Move DISPC timing checks to CRTC .mode_valid() operation

[Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>]

The DISPC timings checks relate to the CRTC, but they're performed in
the encoder and connector .atomic_check() and .mode_valid() operations.
Move them to the CRTC .mode_valid() operation.
