extcon: arizona: Updates for v3.10

Browse source 
There's a bunch of different things in this series, I can split them out
 if need be:
 
  - Support for configuring the button detection circuit to reflect the
    accessories supplied with the system.
  - Improvements in the HPDET based detection scheme.
  - Additional robustness against more pathological use cases.
  - A few small standalone fixes.
