There was another report of a boot failure with a #GP fault in the uncore SBOX initialization. The earlier work around was not enough for this system. The boot was failing while trying to initialize the third SBOX. This patch detects parts with only two SBOXes and limits the number of SBOX units to two there. Stable material, as it affects boot problems on 3.18.
