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.
