[Open-graphics] video controller output clock

[Timothy Normand Miller]

The simplest way is to have a high frequency into a divider.  But
that's kinda limited.  Another thing you can do is take the DCM
output, run that through a divider, and then use the output of that as
feedback.  I think.  I'm really not sure how Howard did it.
