ENGR00214866 MX6SL ARM2, UBoot : Apply V0.91 LPDDR2 Script

Validation team released lateset LPDDR2 script V0.91, See
"http://compass.freescale.net/livelink/livelin
k?func=ll&objId=226435628&objAction=browse&viewType=1"
This change is necessary for bus freq scaling

Apply it for both DCD mode and plugin mode.
