AMD Fam15: Add SPD read functions to wrapper code

Change:
    This is the initial step for moving the AMD F15 & HUDSON1,2,3
    SPD-read callout out of the mainboard directories and into
    the wrapper.  The next step is to update the platforms to use
    this routine in BiosCallouts.c and to delete the code from the
    mainboard directories.  The DIMM addresses should be moved into
    devicetree.cb.
    If there are significant differences or reasons that the mainboard
    needs to override this code, it's perfectly reasonable to keep using
    the version in the mainboard, but this allows us to remove duplicated
    code and simplify the mainboard directories.

Notes:
    This started by duplicating what was in Dinar, and was changed to
    use the devicetree.cb structures.  Significant cleanup and magic
    number reduction was done as well.

It is intended that this file will not be included in ramstage as
    the DIMM init is all done in romstage.

This is similar to what was done for Parmer/Thatcher in commit
    7fb692bd - http://review.coreboot.org/#/c/2190/
    Fam15tn: Move SPD read from mainboards into wrapper

Yes, it would make sense to split this into two separate files
    and move the SMBus initialization and access into the southbridge
    wrapper.  Maybe that can come next.
