dt-bindings: mfd: qcom,spmi-pmic: Drop unused labels from examples

There's not much point in having unused labels in the binding example,
so drop them.

This patch was originally motivated by ea25d61 ("arm64: dts: qcom:
Use plural _gpios node label for PMIC gpios") updating all dts files to
use the plural _gpios label instead of the singular _gpio as label but
this example wasn't updated. But since we should just drop the label
alltogether, do that.
