arm64: dts: qcom: msm8939-sony-tulip: Allow disabling pm8916_l6

The vendor kernel from Sony does not have regulator-always-on for
pm8916_l6, so we should be able to disable it when setting up the
display properly. Since sony-tulip does not have display set up
currently it should be fine to let the regulator disable until then.
