Misguided attempt in the early days of IIO to match hwmon units.
Sadly it is now the ABI and hence 'unfixable'. Same odd units
for voltage and current + a few others that date back to those
days. A big oops. There are some other non obvious bits and
pieces so should always check the ABI docs which should be near
complete.
