Subject: [PATCH] arm64: dts: qcom: sm6125-seine: Clean up gpio-keys (volume down)

- Remove autorepeat (leave key repetition to userspace);
- Remove unneeded status = "okay" (this is the default);
- Allow the interrupt line for this button to be disabled;
- Use a full, descriptive node name;
- Set proper bias on the GPIO via pinctrl;
- Sort properties.

Fixes: 82e1783890b7 ("arm64: dts: qcom: sm6125: Add support for Sony Xperia 10II")
