Subject: [PATCH] arm64: dts: qcom: sc8180x: Enable the power key

From: Bjorn Andersson <quic_bjorande@...cinc.com>

No input events are generated from the pressing of the power key on
either Primus or Flex 5G, because the device node isn't enabled.

Give the power key node a label and enable this for the two devices.
