First round of IIO fixes for the 4.10 cycle. 

* 104-quad-8
   - Fix selecting wrong register when the index control register is desired.
   - Fix an off by one error when addressing the input/output control register.
   - Fix inverted logic on the active high / low control
 * bmi160
   - Sleep for worst case rather than best case amount of time after cmd
   execution begins.
 * max44000
   - typo fix in illuminance_integration_time_available listing.
 * st-sensors
   - Fix channel data passing.  This one took a while to get tested on 24bit
   parts. Definitely one for stable asap as the bug broke quite a few parts.
   - lis3lv02 needs a data alignment bit set and the scaling was wrong.
 * ti_am335x
   - depend on HAS_DMA
