So, it's been a year or so since this was last visited. Time flies.
At that time, Ken Chen gave up and I didn't want to add untested
code. However, Pradeep Srinivasan asked about PCA9641 and so I have
now rebased the preparatory patches to v5.0 and added the bits Ken
wrote on top of the framework I wrote.

Looking forward to some test results, this has only been build-tested.
The actual code that does anything remotely interesting with the
PCA9641 is all Kens work, and I have no knowledge if it works or not.

Changes since last year   (https://lkml.org/lkml/2018/3/20/205)
- rebased to v5.0
- changed a couple of helper functions to return bool instead of int 0/1
- added dt-bindings patch
- warped Kens patch to fit on top of the preparatory work in patches 1-3
