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"
