I would expect fs_device_id to include the partition information. Shell
commands such as ls and load use the following format for the device ID:

controller_id[.hw_partition][:sw_partition]

(with support for the .hw_partition field being part of a patch I sent
to get_device_and_partition() within the last few weeks). Hence, we
don't need separate fields for this. This proposal would unify the way
ls/load/dfu specified devices.
