soc/intel/apollolake: utilize postcar phase/stage

The current Apollolake flow has its code executing out of
    cache-as-ram for the pre-DRAM stages. This is different from
    past platforms where they were just executing-in-place against
    the memory-mapped SPI flash boot media. The implication is
    that when cache-as-ram needs to be torn down one needs to be
    executing out of DRAM since the act of cache-as-ram going
    away means the code disappears out from under the processor.
    Therefore load and use the postcar infrastructure to bootstrap
    this process for tearing down cache-as-ram and subsequently
    loading ramstage.
