We've been lazy and not been updating this file.

 $ git grep "qcom,spmi-gpio"
 arch/arm/boot/dts/qcom-pm8941.dtsi:                     compatible = "qcom,pm8941-gpio", "qcom,spmi-gpio";
 arch/arm/boot/dts/qcom-pma8084.dtsi:                    compatible = "qcom,pma8084-gpio", "qcom,spmi-gpio";
 arch/arm64/boot/dts/qcom/pm8005.dtsi:                   compatible = "qcom,pm8005-gpio", "qcom,spmi-gpio";
 arch/arm64/boot/dts/qcom/pm8998.dtsi:                   compatible = "qcom,pm8998-gpio", "qcom,spmi-gpio";
 arch/arm64/boot/dts/qcom/pmi8994.dtsi:                  compatible = "qcom,pmi8994-gpio", "qcom,spmi-gpio";
 arch/arm64/boot/dts/qcom/pmi8998.dtsi:                  compatible = "qcom,pmi8998-gpio", "qcom,spmi-gpio";

So we'll need to add pm8005, pm8998, pmi8998 here with their pin counts
too to avoid breaking those devices with this patch.
