RADEON: rework MacModel option

this brings in some previous research from Michel Dänzer,
Sjoerd Simons, and myself.  Hopefully, the driver will pick
the correct MacModel in more cases.  This also changes the
default connector table for desktop Macs to dual DVI rather
than DVI+VGA as that seems to be the case more often than not.
External TMDS chips are handled separately now as well.
Eventually we should add an option to allow the user to specify
what external TMDS chip they need, but we don't have enough info
yet, so we'll rely on OF to init the external chip in most cases
for now.
