[PATCH v2] arm64: dts: qcom: eliza-evk: Add power and volume keys

[Abel Vesa]

The Eliza EVK has three tactile switches: SYS_ON, Volume Down,
and Volume Up.

Enable the existing PMK8550 PON power and resin keys for SYS_ON and
Volume Down. Describe Volume Up, which is connected to PM7550 GPIO6.

Do this in the Eliza EVK dtsi so it can be reused by the Eliza CQM EVK
board.

  between CQS and CQM EVK boards.
