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.
