[FIX] hw_drivers: Avoid duplicates identifiers in devices

Before this commit the identifier integrate the BUS and port to identifiate USB devices
Now we check if there are duplicates devices before increment the identifier

For other loop we add identifier in the iot_device object

USB devices are identified by a combination of their `idVendor` and
`idProduct`. We can't be sure this combination in unique per equipment.
To still allow connecting multiple similar equipments, we complete the
identifier by a counter. The drawbacks are we can't be sure the equipments
will get the same identifiers after a reboot or a disconnect/reconnect.
Loops over the connected usb devices, assign them an identifier, instantiate
an `IoTDevice` for them.
