google/oak: increase the driving strength for 4GB DRAMs
Some PVT units encountered DRAM calibration failure during power on/off
tests. The failure is caused by higher impedance of the DRAM on those units.
So increase the driving strength for 4GB DRAMs.
BUG=chrome-os-partner:57392
TEST=run cold reboot 100 times on PVT units which have DRAM calibration issue.
