This structures are not used, and have a single element array at the end
of them. Remove them.

This fix the following cocci warnings:

I realise I'm going against the grain saying this but, I believe these 
structures - which document host <-> firmware data packets - the ABI - 
should be retained in the header, even if they are unused, since they 
are documentary and potentially of future use.

I'd rather fix the WARNING than zap the structure.
