	extcon: arizona: Updates for v3.10

	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.
