x86, cpu: Fix detection of Celeron Covington stepping A1 and B0



Steppings A1 and B0 of Celeron Covington are currently misdetected as
Pentium II (Dixon). Fix it by removing the stepping check.

[ hpa: this fixes this specific bug... the CPUID documentation
  specifies that the L2 cache size can disambiguate additional CPUs;
  this patch does not fix that. ]
