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.
