soc/intel/apollolake: use arch_segment_loaded() for CAR code coherency
Instead of using platform_prog_run() for flushing programs from L1D to L2 for code coherency purposes use arch_segment_loaded() instead as that it's primary purpose. The arch_segment_loaded() is called within the infrastructure at the appropriate places when loading programs. Therefore use that to perform the L1D flush instead of when something is just about to run.
