Subject: [PATCH 1/2] ASoC: dt-bindings: simple-card: add 'hp-pin-name-headphone' property

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'
