amd64_edac: Factor in CC6 save area
F15h and later use a portion of DRAM as a CC6 storage area. BIOS programs D18F1x[17C:140,7C:40] DRAM Base/Limit accordingly by subtracting the storage area from the DRAM limit setting. However, in order for edac to consider that part of DRAM too, we need to include it into the per-node range. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
