Fabio Baltieri 55c14e6fa6 input: analog_axis: rework deadzone calibration code
Rework the data scaling algorithm for the "deadzone" mode so that the
deadzone is subtracted from the input rather than from the output. This
makes the whole output range usable rather than making the output jump
from the center value to the minimum deadzone range.

This changes the calibration data structure as well so now all values
refer to the input data, which is more coherent.

Add an input driver to read data from an analog device, such as a
thumbstick, connected to an ADC channel, and report it as an input
device.
