ENGR00154672: Change to use rom plugins for mx53 boards

1. As customer required, we change to use rom plugins for mx53 boards.
Tested pass with latest mfg tools.
2. Update DDR3 script based on MX53_TO2_DDR3_LCB_SMD_ARDb_v2.inc.
Got from
http://compass.freescale.net/livelink/livelink?func=ll
&objId=221058910&objAction=browse&viewType=1.
3. Fix a tiny build error in mx53_smd.c.
This error will happen when building mx53_smd_mfg.
