The driver itself doesn't really know what parts of the image are which.
I have to ask the firmware. And it doesn't have a "settings only" flag.
I have roughly equivalent to "binary only", "binary + settings" and
"binary + settings + vital fields"
Plus, this means that every update must be single-component and there's
no way to distinguish this when an update is supposed to be for all of
the components in the PLDM file.
