Fix character devices after DisplayState refactoring

The DisplayState refactoring changed the machine init function to create a
DisplayState for each VGA device instead of being passed an existing
DisplayState.  This change is critical to enable multiple graphics device
support.

Unfortunately, the serial/parallel/console code is structured today to run
before machine init to fill out the CharDriverState table which the machine
init function uses to determine whether to create the required devices.

Since a 'vc' is a type of CharDriverState, the CharDriverState code requires
that a DisplayState exist before it runs creating a circular dependency.

To fix this, this splits the creation of the initial CharDriverState from
the initialization of the text console.  We can then in a second step associate
a DisplayState with all TextConsoles.  This allows us to create the
CharDriverState's first, machine init, then associate the TextConsoles with
a DisplayState.

This code screams for more cleanup.
