Some boards have an entirely passive RGB to VGA bridge, based on DACs
implemented by resistor ladders.
Those might or might not have an i2c bus routed to the VGA connector in
order to access the screen EDIDs.
Add a bridge that doesn't do anything but expose the modes available on the
screen, either based on the EDIDs if available, or based on the XGA
standards.

Adapt drm_pick_crtcs() and update_connector_routing() to fallback to
drm_atomic_helper_best_encoder() if funcs->best_encoder() is NULL so
that DRM drivers can leave this hook unassigned if they know they want
to use drm_atomic_helper_best_encoder().
Update the vtables documentation accordingly.

In this case, kernel driver will set wrong mc_clkdis value
when cec enable. So mc_clkdis should be got from uboot.
