northbridge/intel/sandybridge: Fix random raminit failures

Issue observed:
        Intel raminit works in about 50% of all test-cases on lenovo x220.

Problem solution:
        Prefer a smaller valid value over the measured one for
        initial timB timings.

Final testing result:
        Tests on x220 shows that the issue was resolved.
        The test system booted successfully ten times in a row.
        Tests on Gigabyte GA-B75M-D3H revealed no regressions.

Test system:
        * Intel Pentium CPU G2130
        * Gigabyte GA-B75M-D3H
        * DIMM: "Crucial 2GB 256Mx64 CT2566aBA160BJ"
