Enable dm support for USB (which also requires dm support for fixed regulators used for vbus enable) and remove usb iomux which is no longer needed. We can remove the handling of otgpwr_en gpio as this is defined in dt as usbotg vbus-supply but we need to keep the handling of USB_HUB_RST# for boards that have a USB HUB as that isn't defined in the dt's currently.
