RAS/AMD/FMPM: Get masked address
Some operations require checking, or ignoring, specific bits in an address
value. For example, this can be comparing address values to identify unique
structures.
Currently, the full address value is compared when filtering for duplicates.
This results in over counting and creation of extra records. This gives the
impression that more unique events occurred than did in reality.
Mask the address for physical rows on MI300.
[ bp: Simplify. ]
