ARM: dts: imx: ventana: add LTC3676 PMIC support
All of the Gateworks Ventana boards based on the IMX6 SoC except for the GW54xx use the LTC3676 PMIC. Add a device-tree node with interrupt support for this PMIC. Additionally remove the simple-bus notation in the regulator nodes and any fixed regulators that are provided by the PMIC.
