amd/stoneyridge: Create an MCA structure
Convert the Machine Check reporting to use a newly defined structure. This will facilitate later patches that will pass pointers to the MSR values. BUG=b:65446699 TEST=inspect BERT region, and dmesg, on full patch stack. Use test data plus a failing Grunt system.
