haswell: add romstage_after_car() function

There are changes coming to perform more complex tasks after cache-as-ram
    has been torn down but before ramstage is loaded. Therefore, add the
    romstage_after_car() function to call after cache-as-ram is torn down.
    Its responsibility is for loading the ramstage and any other complex
    tasks. For example, the saving of OS-controlled memory in the resume
    path has now been moved into C instead of assembly.
