arm64: dts: qcom: msm8916-alcatel-idol347: add LED indicator

Browse Source 
Add si-en,sn3190 LED controller to enable white LED indicator.

This requires adding the additional "enable" gpio that the OEM
choose to use, despite it not being mentioned in si-en,sn3190
datasheet nor supported by the driver.
