This adds an ADC driver for the STMPE device using the industrial
input/output interface. The driver supports raw reading of values.
The driver depends on the MFD STMPE driver. If the touchscreen
block is enabled too, only four of the 8 ADC channels are available.

Changes in v3:
 - Undo ADC-settings related code-deletions in stmpe-ts.c that the code is
   backwards-compatible to older devicetrees.

Changes in v2:
 - Code formatting
 - Move code to setup ADC to MFD device, as it is used by both drivers
   adc and touchscreen
 - Removed unused includes
 - Defined the macro STMPE_START_ONE_TEMP_CONV with other macros.
 - Added new macro that defines the channel of the temperature sensor.
   Took new name for STMPE_MAX_ADC->STMPE_ADC_LAST_NR and used it throughout
   the code for better readability.
 - Added mutex_unlock where missing.

The MFD changes should be contained in a separate patch.

I don't see anything which ties the changes together.
