Only FW versions which are updated with a single flashing operation /
are part of a single FW image should be reported under the device
instance. If the flash is separate you need to create a separate
devlink (sub)instance or something along those lines.

Differently put - the components in the API are components of the FW
image, not components of a board.

We had a similar discussion about "line cards" before.
