I wonder if this is a useful.  The RM code that tests for these sizes is auto-generated, so it
automatically matches.  Contrast that with the ELF image that is provided to Nouveau, where the
sizes are specified in the section header.  

Let's say we update the firmware again, and the newer firmware works as-is, but some of the metadata
sizes are different (e.g. size_pkey is 113).  We would need to create a new version-specific struct,
despite the fact that the ELF image already tells you everything you need to know.
