Second set of IIO fixes for the 4.7 cycle.

Browse Source 
This includes one tracked regression (Arnd's patch for the ad7606).
 The other two have I think always been broken.
 
 * inv_mpu6050
   - Fix a use after free in the ACPI code.
 * ad5933
   - The code for setting the cycles had a bug that meant it was simply wrong.
 * ad7606_spi
   - Fix a regression that got introduced in a buggy cleanup of a sparse
     warning.
