The 'Headphones Jack' name used in current simple-card and audio-graph
card driver can't be recognized by user space service daemon like
pulseaudio and pipewire, which only recognize the 'Headphone Jack',
so add 'hp-pin-name-headphone' property for this case and it won't block
original use cases for 'Headphones Jack'

If the DT binding is not a choice, shall I change the "Headphones" to
"Headphone"
directly? I don't know if this change will block any case?
pin_name = pin ? pin : "Headphone";

That's different name than you defined in the bindings.
