Some devices use a headset mic bias supply (sometimes referred to as "ear mic bias") to enable/disable the headset mic.
Add a REGULATOR_SUPPLY widget for this supply which gets the headset- mic-bias supply and is routed to the Headset Mic switch similar to how it's done for the other mic bias regulators.
