siemens: update DDR3 parameters for dxr2
* add parameters for factory and print them at start up to facilitate control of right DDR3 settings in EEPROM. * cosmetic changes in a couple of printfs Signed-off-by: Samuel Egli <samuel.egli@siemens.com> Cc: Roger Meier <r.meier@siemens.com> Cc: Heiko Schocher <hs@denx.de> Cc: Wolfgang Denk <wd@denx.de>
