nb/intel/x4x/raminit: Fix DIMM_IN_CHANNEL calculation

Fix-up for 696abfc
      nb/intel/x4x: Fix and deflate `dimm_config` in raminit

It didn't fix the channel-number shifting issue as intended.

The channel index is either 0 or 1. DIMMs are counted from 0
    to 3 where 0..1 covers channel 0, and 2..3 covers channel 1.
    Since we have two DIMMs per channel, we have to multiply the
    channel index by 2 (or shift it left by 1) to get the index
    of the first DIMM in the channel. Finally, to get the offset
    of a DIMM in the channel we take its index modulo 2 (again,
    the number of DIMMs per channel).
