imx: ventana: put LTC3676 regulators in continuous mode
In the default pulse-skipping mode regulators that are very lightly loaded can fail to regulate properly. Switching them to always use continuous mode causes only around 10mW of overall system power difference in a lightly loaded system that isn't already operating them in continuous mode.
