First set of IIO fixes for the 4.9 cycle.

* atlas chemical
   - Fix alignment of big endian values in a larger storage (by using the right
   size storage)
 * maxim thermocouple
   - Fix alignment of big endian values in larger (by using the correct
   sized storage).
 * sca3000
   - Handle unexpected mode values.
 * ti-adc081
   - Select IIO_TRIGGERED_BUFFER to avoid build errors
