mb/prodrive/atlas: Add IBECC Kconfig option

Add an option on Atlas to enable IBECC (In Band Error Correction Code),
which is currently needed for endurance testing.

Test: start atlas mainboard with Linux. See in dmesg that
IBECC (EDAC igen6) driver is loaded. Inject a fake error via debugfs
and see in dmesg that Linux handles it.
