Hm.. doesn't the console setup happen before the port is opened though?
I would think that we need to keep this around so that the clock is
actually enabled before we go and write to hardware registers.

I wonder if we should leave this here? Maybe we can rely on the user
specifying the right values on the command line?

msm_port is unused now. Please remove it in the same patch.
