Various cosmetic and coding style fixes in src/devices.
Also:
- Improve a few code comments, fix typos, etc.
- Change a few more variable types to u8/u16/u32 etc.
- Make some very long lines fit into 80chars/line.
- Drop a huge duplicated comment, use "@see" to refer to the other one.
- Reduce nesting level a bit by restructuring some code chunks.
- s/Config.lb/devicetree.cb/ in a few places.
Abuild-tested.
