MLK-19098 ARM: dts: imx7ulp-evk: use OTG ID function instead of GPIO

Browse Source 
Since IMX7ULP_PAD_PTC13 has OTG ID function, so change the iomux
to be OTG ID instead of GPIO, with that we can use usb ID event
directly for role switch, which is more quick than extcon driver.
which also help on pass the type-C compliance test: "TD 4.5.6 DRP
connect Try.SNK DRP Test"
