Third round of iio fixes for the 3.16 cycle.

* Lots of hid sensors component drivers had a bug due to a local variable
  whose name suggested it was returned from the read_raw function not
  infact being returned (ret vs ret_type).  Fixed and unused ret removed.
* Block a possible race condition in tcs3472 by locking around some
  dependant i2c messages.
* Fix bug in the am335x driver fifo setup that occurs if the final
  channel enabled takes certain values.
