arm64: dts: qcom: sc8180x-flex-5g: remove superfluous "input-enable"

Pin configuration property "input-enable" was used with the intention to
disable the output, but this is done by default by Linux drivers.  Since
commit c4a48b0df8bf ("dt-bindings: pinctrl: qcom: tlmm should use
output-disable, not input-enable") the property is not accepted anymore.
