x86, MCE, AMD: Drop software-defined bank in error thresholding
Aravind had the good question about why we're assigning a software-defined bank when reporting error thresholding errors instead of simply using the bank which reports the last error causing the overflow. Digging through git history, it pointed to 95268664 ("[PATCH] x86_64: mce_amd support for family 0x10 processors") which added that functionality. The problem with this, however, is that tools don't know about software-defined banks and get puzzled. So drop that K8_MCE_THRESHOLD_BASE and simply use the hw bank reporting the thresholding interrupt. Save us a couple of MSR reads while at it.
