When using device tree the USB driver for the imx family is the
chipidea driver. The driver you used reviously without DT does not
work with DT.

There is a mx35 dts file that has otg support. You can use
arch/arm/boot/dts/imx35-eukrea-cpuimx35.dtsi as reference:
&usbotg {
phy_type = "utmi";
dr_mode = "otg";
external-vbus-divider;
status = "okay";
};
