google/eve: Fix DRAM DQS map

This change fixes the two sets of pins that were swapped in the
map of DQS signals from CPU to DRAM for channel 1.

Although this does not appear to have any impact to the system it
does result in different register values for DQS pin mapping that
are programmed inside FSP.

BUG=chrome-os-partner:58666
TEST=This fix was verified against the current schematic and using
FSP debug output.
