haswell: unify romstage logic

This commit pulls in all the common logic for romstage into
    the Haswell cpu directory. The bits specific to the mainboard
    still reside under their respective directories. The calling
    sequence bounces from the cpu directory to mainboard then back
    to the cpu directory. The reasoning is that Haswell systems use
    cache-as-ram for backing memory in romstage. The stack is used to
    allocate structures. However, now changes can be made to the
    romstage for Haswell and apply to all boards.
