These comedi drivers are all very similar so it made sense to clean them
up together.

This series removes a bunch of the cruft in the drivers and reduces the
boardinfo and private data.

I don't agree with patch 31 (staging: comedi: pcl816: remove incorrect 'ai_chanlist' from boardinfo). I don't think dropping that patch has any knock-on effects on the other patches.

For patches 01 to 30, 32 to 87:
