x86/mce/AMD: Reduce number of blocks scanned per bank >From Fam17h onwards, the number of extended MCx_MISC register blocks is reduced to 4. It is an architectural change from what we had on earlier processors. Although theoritically the total number of extended MCx_MISC registers was 8 in earlier processor families, in practice we only had to use the extra registers for MC4. And only 2 of those were used. So this change does not affect older processors. Tested on Fam10h and Fam15h systems.
