    soc/apollolake: Enable all CPU cores using the parallel MP lib
    
    This is the minimal setup needed to get all CPU cores enabled. That
    includes sending an IPI to APs and setting up MTRRs. Microcode updates
    are not performed for two reasons:
    * CSE upgrades the microcode before releasing reset
    * Microcode update files are not available at this point in time
