Fill in PowerSupply::updateInventory()

This function will read the power supply's CCIN,
part number, serial number, and firmware version
from the supply and then write them to the supply's
inventory object.

If the supply isn't present, it will write empty values
to the inventory, so stale values won't be left in the
case that something was removed.

The Purpose property on the Software.Version interface
also always needs to get written to 'Other', otherwise
it defaults to 'Unknown'.

The CCIN was chosen as the closest thing available for
use in the Model property.

Resolves openbmc/openbmc#1782
