    sandybridge: Disable parallel CPU initialization
    
    Disable the parallel CPU initialization for model_206ax, that is Sandy
    Bridge and Ivy Bridge processors. We never did it the way that Intel
    recommends and it became unreliable with the introduction of SMM_MODULES
    in commit a3e41c0 Migrate 206ax to SMM_MODULES.
    
    Tested by booting kontron/ktqm77 2.6k times into Linux user space. No
    issues so far.
