i2c: mv64xxx: refactor message start to ensure proper initialization
Because the offload mechanism can fall back to a standard transfer, having two seperate initialization states is unfortunate. Let's just have one state which does things consistently. This fixes a bug where some preparation was missing when the fallback happened. And it makes the code much easier to follow. To implement this, we put the check if offload is possible at the top of the offload setup function.
