sensor: Adjust max_frequency based on EC performance
Put in max_frequency a value that the sensor AND the EC support.
BRANCH=none
BUG=b:118205424,b:118851581,chromium:615059
TEST=Compile. Check all max sensors frequencies have been altered with:
for i in $(grep -rh max_frequency board | cut -d '=' -f 2 | sort | \
uniq | grep FREQ | sed 's/FREQ.*//') ; do
echo -n $i ; git show | grep -q $i || break;
echo check
done
Check on nocturne accel max frequency is still correct.
