arcada_ish: add base lis2dh accel sensor

Add base accelerometer to arcada_ish image. Lid angle detection using
base and lid accel sensors in EC is still pending.

With draft CLs, I successfully calibrated this sensor and calculated lid
angle successfully using the AccelerometersLidAngleTest factory test in
the AP.

BRANCH=none
BUG=b:122281217
TEST=sensors is calibratable with normal factory calibration process and
usable for lid angle calculation using factory tests.
