The mcp3021 scaling code is dividing the VDD (full-scale) value in
millivolts by the A2D resolution to obtain the scaling factor. When VDD
is 3300mV (the standard value) and the resolution is 12-bit (4096
divisions), the result is a scale factor of 3300/4096, which is always
one.  Effectively, the raw A2D reading is always being returned because
no scaling is applied.

This patch fixes the issue and simplifies the register-to-volts
calculation, removing the unneeded "output_scale" struct member.

As per Documentation/hwmon/sysfs-interface, hwmon name attributes must

The function get_ohm_of_thermistor has both the measured voltage and the
pullup voltage available in microvolts.  But it was promptly converting
both to millivolts before using them to calculate the thermistor
resistance.  That conversion unnecessarily hurt the precision of the
calculation.

For example, take the ncpXXwb473 connected to 5000 mV and pulled down
through a 47000 ohm resistor.  At 25 C, the resistance of the thermistor
is 47000 ohms.  The measured voltage will be 2500 mV.  If we measure
instead 2501 mV, then the calculated resistance will be 46962 ohms --
a difference of 38 ohms.  So the precision of the resistance estimate
could be increased by 38X by doing the calculations in microvolts.

The function ntc_adc_iio_read was assuming both a 12 bit ADC and that
pullup_uv is the same as the ADC reference voltage.  If either
assumption is false, then the result is incorrect.

Attempt to use iio_convert_raw_to_processed to convert the raw value to
microvolts.  It will fail for iio channels that don't support support
IIO_CHAN_INFO_SCALE; in that case fall back to the assumptions.
