some minor dal cleanups and example of future patches

So whenever I look at DAL I find myself trying to figure out what all of it does, and this leads me to deleting things, so I'm just sending out some stuff that I cleaned today. One thing I noticed in passing is the displayport code seems possibly endian unsafe, it casts bytes read from hardware
