usb: chipidea: imx: enable OTG overcurrent in case USB subsystem is already started
When initializing the USB subsystem before starting the kernel, OTG overcurrent detection is disabled. In case the OTG polarity of overcurrent is low active, the overcurrent detection is never enabled again and events cannot be reported as expected. Because imx usb overcurrent polarity is low active by default, only detection needs to be enable in usbmisc init function.
