	ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs

	This patch series covers both ASoC and extcon subsystems and fixes an
	interaction between the HPDET function and the headphone outputs - we
	really shouldn't run HPDET while the headphone is active.  The first
	patch is a refactoring to make the extcon side easier.
