[PATCH 07/11] arm64: dts: qcom: sc8280xp-arcata: Add volume up/down GPIO keys

[Jérôme de Bretagne via B4 Relay <devnull+jerome.debretagne.gmail.com@kernel.org>]

From: Jérôme de Bretagne <jerome.debretagne@gmail.com>

Configure gpio6 to serve as volume down and gpio9 as volume up to enable
the volume up/down keys located at the top of the screen.
