AMD Steppe Eagle: Add northbridge files for new SoC family

Add the northbridge file for AMD's new Mullins and Steppe Eagle
    processor family.  Since the processor family name is not the
    same across AMD's sales and marketing channels, I have elected
    to use part of the processor ID as the family name.  The intent
    is to reduce confusion since the processor ID is the same for
    both families.  This northbridge support has only been validated
    on the AMD Embedded variants ("Steppe Eagle").

The AGESA wrappers in coreboot have a function that is intended to
    mirror the UMA memory allocation performed during memory initialization
    by AGESA.  Update the Steppe Eagle memory allocation to mimic the
    memory reservation done inside the AGESA BLOB.

Change the default CBMEM address, the default video BIOS device ID,
    and a couple of other defaults to match changes in coreboot community
    code.

The northbridge chip.h specifies how many processor sockets, how
    many channels, and how many DIMM slots are supported by the
    northbridge.  Steppe Eagle does not permit multisocket systems
    and has only one memory controller channel.
