mb/google/dedede: Enable CSE Board Reset Override

This will ensure that the cold reset is performed when CSE Lite jumps
from RO to RW.

BUG=b:162386991
TEST=Ensure that Drawcia board boots to OS. Ensure that global reset is
triggered when cr50 is running firmware versions newer than 0.0.22. On
cr50 versions 0.0.22 or older, EC triggers cold reset of AP.
