Move setup_uma_memory() to K8 northbridge

These boards had identical UMA code:
  amd/dbm690t
  amd/pistachio
  technexion/tim5690
  technexion/tim8690

The ones below had whitespace or debug level change
compared to the one above:
  kontron/kt690
  siemens/sitemp_g1p1

These boards use AMDFAM10 guidelines in code:
  asrock/939a785gmh
  amd/mahogany
