drop unneeded firmware name in docdef

For reasons I haven't been able to tease apart yet, loading a preset file from disk is failing unless I remove this field. This isn't used for anything, it's just a marker at the start of the file that says it is an Ansible preset, which the filename already tells you.

@csboling anything else needed prior to a ansible release? if not i can get one ready

@tehn With this I think a release is fine and there are a number of things it would be nice to get out. I'm currently working on adding W/syn i2c support (should be pretty easy, a few people have asked about this) and perhaps also crow i2c support, so there may be some more features here in like a week, but it's probably good to let people beta test those rather than just putting them in the release?

that sounds fantastic. @trentgill is likewise pushing norns and w/2 support, so this might all land at once.
