nb/intel/sandybridge/raminit: Fix CAS Write Latency
As documented in DDR3 spec for MR2 the CWL is based on DDR frequency.
There's no to little difference for most memory modules operating at DDR3-1333.
It might fix problems for memory modules that operate at a higher frequency and
memory modules with low CL values should work even better.
Tested on Lenovo T420 with DDR3-1333 CL9 and DDR3-1600 CL11.
No regressions found.
