Do this as we don't want to use this functionality on our Carrier Boards and to leave it open to someone who includes our module-level device-trees. Remove the now obsolete disable-over-current flag from module-level device-tree imx8mm-verdin.dtsi and leave it as already mentioned to the people actually implementing the carrier-board to implement this. This will prevent the warning "No over current polarity defined" from being printed on boot.
