    soc/intel/apollolake: use platform_segment_loaded() for CAR coherency
    
    Instead of using arch_segment_loaded() implement
    platform_segment_loaded() so as not to tangle the notion of
    arch and the chipset. Lastly, add a TODO to allow filtering
    of the L1D to L2 flush depending on the region loaded.
