EDAC/intel-bff: Compute unique ID for overflowed filter

Each L2 cache instance has its own bitfix filter, but always reports
errors in machine check bank 3 (on Diamond Rapids).

Compute a unique bitfix filter instance number based on the CPU that
logged the error and the machine check bank number.

Special-case the banks associated with the Integrated Memory Hub (IMH).
Here the "even" numbered CPU modules are associated with IMH0 and the
"odd" modules with IMH1.

The unique id will be used to store a time stamp of when the bitfix
filter overflowed so that frequent overflows can be logged.
