ARM: dts: qcom: apq8026: 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
patch ("dt-bindings: pinctrl: qcom: tlmm should use output-disable, not
input-enable") the property is not accepted anymore.
