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

[Abel Vesa]

The Eliza CQS 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.

Can this go to eliza-evk.dtsi instead?

They can, but what happens if the CQM variant remaps them to some
different gpio? I don't know what CQM looks like. I guess we can hope
they do not change.

Just discussed it with the HW engineer. It is the same on CQM.

So I'll move it to eliza-evk.dtsi instead.

Thanks for reviewing.
