iio: vadc: Qualcomm SPMI PMIC voltage ADC driver 



The voltage ADC is peripheral of Qualcomm SPMI PMIC chips. It has
15bits resolution and register space inside PMIC accessible across
SPMI bus.

The vadc driver registers itself through IIO interface.

	  This is the IIO Voltage ADC driver for Qualcomm QPNP VADC Chip.



	  The driver supports multiple channels read. The VADC is a 15-bit
