psu-ng: Validate configuration during power on

Create a function to validate the power supply configuration. Initially,
check that all power supplies are of the same model, and if not, create
an error log. This function will later add checks for total number of
power supplies and expected input voltage.

The validation is run on every power on. To cover the case where entity
manager has not run yet on power, trigger the validation on interfaces
added signal. Use a boolean flag to determine if the validation needs to
be run to avoid running it multiple times.

Tested: Verified the validation was successful on Rainier.
        Verified the error log data:
