board: Set Accelerometer range to 4g
Required by Android CDD - Section 7.3.1 - Paragraph C.1.4
Modified mechanically with:
for i in $(grep -lr "\.default_range" board); do
sed -i '/.default_range =/s#\(.*\.default_range = \).* /\
\* g.*#\14, /* g, to meet CDD 7.3.1/C-1-4 reqs */#' $i
done
Manually reworked to only change the accelerometer that matters to
android:
The lid accelerometer or the base accelerometer if the base also hosts
the gyroscope.
This is only for future EC, no need to land the change on branches:
mems_setup will take care to set accelerometer ranges at 4g on startup.
BUG=b:144004449
BRANCH=none
TEST=compile
