mkmpioboot: restructure model / firmware file information.

Browse source 
Collect the various arrays holding model names, numbers etc. into a
structure. This makes the code cleaner since there aren't multiple
arrays that need to be kept in sync any more and avoids issues with
other tools (like mkamsboot) when linked together with Rockbox Utility.
