psu-ng: Read and validate input voltage

Read the input voltage reported by pmbus for each PSU. Determine the
actual voltage based on predefined thresholds. Then validate the actual
voltage is supported for the PSU model.

Tested:
Verified in Rainier 2U that the 2 present PSUs had a pmbus
voltage value of 208000 mV, which is then translated to a 220V PSU, and
that value is validated against the supported configuration.
Verified the additional data strings by printing them with debug
statements:
