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.
