imx: ventana: set LTC3676 PMIC to appropriate values per datasheet
The IMX6 Datasheets specifies that when the IMX6 LDO is enabled
(internal Anatop LDO's for VDD_ARM, VDD_SOC, and VDD_xPU) you need to
provide 1350mV on VDD_ARM_IN and VDD_SOC_IN for IMX6Q@1GHz (Automotive)
and 1275mV for IMX6DL@800MHz (Industrial). While we are still about 50mV
shy on the IMX6Q operating at 1GHz we set it to the max we can and leave it
up to the kernel to implement a regulator driver for the LTC3676 and put
the LDO's in bypass mode which allows us to drop the voltages by 125mV
respectively.
