nb/intel/x4x: Add DDR3 JEDEC init

Add DDR3 JEDEC init (Power up and Initialization by setting emrs regs)

This also modifies the send_jedec_cmd function as DDR3 dimms can have
ranks mirrored which needs to be accounted for.

The ddr3_emrs1_config array is placed externally since it is also
needed for write leveling.
