Subject: [PATCH v5 2/2] arm64: dts: qcom: sdm845-oneplus: Add alert-slider

From: Gergo Koteles <soyer@....hu>

The alert-slider is a tri-state sound profile switch found on the
OnePlus 6, Android maps the states to "silent", "vibrate" and "ring".
Expose them as ABS_SND_PROFILE events.
The previous GPIO numbers were wrong. Update them to the correct ones.
