HID: playstation: Support DualSense audio jack event reporting

The DualSense controller complies with v1.0 of the USB Audio Class spec
(UAC1), hence it cannot advertise any jack detection capability.

However, this feature can be implemented in the generic USB audio driver
via quirks, i.e. by configuring an input handler to receive hotplug
events from the HID driver.

When operating in USB mode, register a dedicated input device for the
audio jack and use it to report all headphone and headset mic insert
events.
