    intel raminit: properly handle DDR3 DIMMs with address mirroring
    Issue observed:
    DDR3 DIMM with address mirroring enabled doesn't work when placed in
    slot 1 and slot 0 is empty. It does work when placed in slot 0 and
    slot 1 is empty.
    Test system:
    * Intel IvyBridge
    * Gigabyte GA-B75M-D3H
    * Kingston KVR1066D3N7/4G (address mirroring enabled DIMM)
    Problem description:
    The address mirror enable bit is slot-swapped in the DIMM mapping code,
    but none of the remaining code is aware of DIMM mapping. Removing the
    code, that is swapping the mirror enable bit, results in the correct
    behaviour. The DIMM is now working in every slot.
