x86/MCE/AMD: Define a function to get SMCA bank type

Browse source

commit 11cf887728 upstream.

Scalable MCA systems have various types of banks. The bank's type
can determine how we handle errors from it. For example, if a bank
represents a UMC (Unified Memory Controller) then we will need to
convert its address from a normalized address to a system physical
address before handling the error.

[ bp: Verify m->bank is within range and use bank pointer. ]
