Properties with standard unit suffixes already have a type and don't need type references. Fix a few more cases which have gotten added.

The CM3605 is an entirely analog part. However, it requires quite a bit of
|
|
software logic to interface a host operating system.
|
|
|
|
This ALS and proximity sensor was one of the very first deployed in mobile
|
|
handsets, notably it is used in the very first Nexus One Android phone from
|
|
2010.
