Add update power supply inventory stubs and calls

This function will read values from the power supply
and put them into the inventory.

This commit doesn't deal with what is written, but it is
properties like the part and serial numbers.

It needs to be called:
* On startup, regardless of presence state.
* When a power supply is added, after the hwmon directory
  has been determined, to read the values for the new unit
* When a power supply is removed.

When the function is called when the unit isn't present,
it will just write empty values to the inventory.  This ensures
when a unit is removed that it doesn't contain stale values.
