Support for Power Button

It seems that the PMC8180A handles the power-button in some non-trivial way. This already seems to be implemented in pmc8180.dtsi as:

&spmi_bus {
	pmc8180_0: pmic@0 {
		compatible = "qcom,pm8150", "qcom,spmi-pmic";
		reg = <0x0 SPMI_USID>;
		#address-cells = <1>;
		#size-cells = <0>;

		pon: power-on@800 {
			compatible = "qcom,pm8916-pon";
			reg = <0x0800>;
			pwrkey {
				compatible = "qcom,pm8941-pwrkey";
				interrupts = <0x0 0x8 0x0 IRQ_TYPE_EDGE_BOTH>;
				debounce = <15625>;
				bias-pull-up;
				linux,code = <KEY_POWER>;

				status = "disabled";
			};
		};
	};
};

It is currently disabled by default. We should test whether this works.
