drm: vc4: Use crtc->mode_valid() and encoder->mode_valid() callbacks
Now that we have a callback to check if crtc and encoder supports a
given mode we can use it in vc4 so that we restrict the number of
probed modes to the ones we can actually display.
Also, remove the mode_fixup() calls as these are no longer needed
because mode_valid() will be called before.
