northbridge/intel/pineview: Add native raminit

Does native ram init for Intel Atom D5xx 8086:a000 northbridge

Tested on Intel D510MO mainboard, board boots linux kernel

- Works fully with both dimms populated (2x2GB), memtest passes 100%
    - Almost boots with only one dimm in one of the slots
      (suspect bad memory map with one dimm?)
    - Reads garbage with only one dimm in other slot
