Currently SoCs pass2.x do not emulate EA headers for ACPI boot method at all.
However, for pass2.x some devices (like EDAC) advertise incorrect base addresses
in their BARs which results in driver probe failure during resource request.
Since all problematic blocks are on 2nd NUMA node under domain 10 add necessary
quirk entry to obtain BAR addresses correction using EA header emulation.
