nb/intel/sandybridge/raminit: Fix dual DIMM command rate
On boards that are able to take two DIMMs per channel the
command rate should be 2T. It is possible to use 1T with
load reduced "1T" DIMMs, but it's not clear how to detect
those DIMMs. Raminit might fail for those who do not have
such DIMMS installed.
Hardcode command rate of 2T to make sure raminit works on
dual DIMM per channel boards (currently only desktop boards).
The command rate of 1T is still tested if only 1 DIMM per
channel is present.
Will decrease performance on quad slot mainboards, if two DIMMs
are installed in one channel and previously 1T have been selected.
Tested on ASRock B75 Pro3-M.
