soc/intel/apollolake: use CAR code coherency for all CAR stages

The flush L1D to L2 operation was only being used when loading
    romstage from bootblock. However, when the FSP-M component is
    loaded no code coherency actions are taken. I suspect this is
    because the FSP-M component is larger than the 24KiB L1D and
    the entry point is early in the image. Thus, when loading
    the FSP-M component the earlier part of the image is flushed
    out to L2 in the process of loading the latter part of the
    component. Also, once verstage is introduced the same
    code coherency actions need to be taken as well. Therefore,
    position the apollolake code to handle all these cases.
