pistachio: Decrease DDR ODT from 75R to 50R
The DDR On Die Termination was incorrectly configured at 75R,
where as the data sheet suggests for DDR2-800 it should be
set to 50R.
Correct this by adjusting the ODT setting in the EMR register.
BUG=chrome-os-partner:31438, chrome-os-partner:37087
TEST=tested on Pistachio bring up board -> DDR initialized
properly and ramstage executed correctly
BRANCH=none
