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.
BUG=chrome-os-partner:27320
TEST=Compile-only. Tested in future Samus commit.
BRANCH=None.
