This is a very valid question, and the current situation probably is
the result of it not having a simple answer.

We could create drivers/accelerometer and move the drivers there for
the time being. Or we can move them to drivers/misc until iio is
merged. Honestly, it would be great if iio could be finally merged, it
would help driver authors get their driver in good shape and in the
right place right away. But I know Jonathan is busy and I can't blame
him if things take time.

All in all, I don't really care where the drivers go, as long as it's
not in drivers/hwmon. So the choice is probably better left to the
authors of the accelerometer drivers. Once one driver is moved, the
rest will have to follow.
