EDAC/igen6: Fix conversion of system address to physical memory address

Browse source 
commit 0ad875f442e95d69a1145a38aabac2fd29984fe3 upstream.

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.
