EDAC/mce_amd: Add support for FRU text in MCA
A new "FRU Text in MCA" feature is defined where the Field Replaceable
Unit (FRU) Text for a device is represented by a string in the new
MCA_SYND1 and MCA_SYND2 registers. This feature is supported per MCA
bank, and it is advertised by the McaFruTextInMca bit (MCA_CONFIG[9]).
The FRU Text is populated dynamically for each individual error state
(MCA_STATUS, MCA_ADDR, et al.). Handle the case where an MCA bank covers
multiple devices, for example, a Unified Memory Controller (UMC) bank
that manages two DIMMs.
[ Yazen: Add Avadhut as co-developer for wrapper changes. ]
[ bp: Do not expose MCA_CONFIG to userspace yet. ]
