all the connector table cares about is whether it's external or
internal TMDS.  we'd need a way to detect or hardcode the external
TMDS chip.  Unfortunately, it seems all sil chips have the same values
for vendor and chip id, so that's useless.  We can either
change/extend the MacModel range or add another option to specify the
external chip.  I only wonder if each variant programs the same
external chip differently.  ugh.
