Replace the deprecated drm_bridge_funcs.mode_fixup() with
drm_bridge_funcs.atomic_check().

drm_bridge_funcs.atomic_check() requires the atomic state operations,
update these to the default implementations.

Hi Sam,

Thank you for the patch.

I'd move this one line down, in alphabetical order.

Shouldn't this be moved to atomic_enable ? A test commit should change
the device state.

As this code was initially in mode_fixup I suppose this patch could be
merged as-is, with the problem fixed on top, so
