  sfxge: infer external port numbering for Pavia
  
  Adjust external port mapping table to distinguish Pavia from Monza.
  Now the presence of any 40G mode implies at least 2 outputs per
  external port.  So Pavia 4x10G ports are now mapped to 1,2,3,4;
  Monza 4x10G ports map to 1,1,2,2 as before.
