iio: adc: add ADC driver for the TI TSC2046 controller
Basically the TI TSC2046 touchscreen controller is 8 channel ADC optimized for
the touchscreen use case. By implementing it as an IIO ADC device, we can
make use of resistive-adc-touch and iio-hwmon drivers.
Polled readings are currently not implemented to keep this patch small, so
iio-hwmon will not work out of the box for now.
So far, this driver was tested with a custom version of resistive-adc-touch driver,
since it needs to be extended to make use of Z1 and Z2 channels. The X/Y
are working without additional changes.
