Fourth set of IIO new device support, features and cleaups for the 4.10 cycle.

Probably the final set before the merge window unless things get significantly
delayed.

New device support
* STM32 ADC core
  - new driver.  Interesting device with up to 3 ADCs with complex triggering
    options that will follow later. Note split into an 'mfd like' core that
    handles the interrupt sharing etc between the various instances present and
    a per ADC section that is instantiated as many times as needed.
  - device tree bindings.

Cleanups and minor fixes
* st_accel
  - inline per sensor data as the defines don't add any meaning and make it
    much harder to check if a given sensor has the right values.
* hid-magnetometer
  - sort out the associations of the associated attributes with the two types.
