EDAC/igen6: Fix conversion of system address to physical memory address
The conversion of system address to physical memory address (as viewed by
the memory controller) by igen6_edac is incorrect when the system address
is above the TOM (Total amount Of populated physical Memory) for Elkhart
Lake and Ice Lake (Neural Network Processor). Fix this conversion.
