EDAC/i10nm: Fix Granite Rapids ADXL MC mapping
ADXL reports memory errors using memory-controller physical indices,
while the EDAC driver identifies memory controllers using logical
indices. On Granite Rapids systems, BIOS may disable some memory
controllers, causing the physical and logical indices to differ.
As a result, ADXL memory errors may be associated with the wrong memory
controller, preventing EDAC from reporting errors for some DIMMs.
Maintain a physical-to-logical MC mapping so that ADXL memory errors are
decoded correctly regardless of the BIOS memory-controller
configuration.
