Refactor accel / gyro driver to accomodate various configurations

Previously our accel / gyro drivers assumed that we had exactly two of
each identical part in the system. Some systems may have different
configurations, so allow this to be specified at the board-level.

Note that our motion_sense algorithm currently assumes that we have one
accelerometer in the lid and one in the base -- we'll need to fix that
in another CL.
