Subject: [PATCH 3/6] ASoC: mediatek: mt8186-da7219: Add headset widgets with switches

Add DAPM widgets for headphones and headset microphone, with matching
switches, to allow toggling these paths based on the jack connection
status.

Note that differently from others (mt8192, mt8195 and mt8186-rt5682),
the widget here is named "Headphones" (with an 's'), since "Headphone
Switch" was already registered by da7219.
