Add support for the Intel Atom D400/500- and N400-series integrated 

northbridge. Also add support for the very similar Q963/965 northbridge.
Tested: 
  D510: confirmed working, with MCHBAR enable code
  Q965: writes to bit 0 to enable MCHBAR access are ignored, all other functions work

Untested:
  D410/D525/N400: should be the same northbridge
