This adds support for the USB PHY in Vybrid VF610. We assume that the disconnection without VBUS is also needed for Vybrid.
Tests showed, without MXS_PHY_NEED_IP_FIX, enumeration of devices behind a USB Hub fails with errors: [ 215.163507] usb usb1-port1: cannot reset (err = -32) [ 215.170498] usb usb1-port1: cannot reset (err = -32) [ 215.185120] usb usb1-port1: cannot reset (err = -32) [ 215.191345] usb usb1-port1: cannot reset (err = -32) [ 215.202487] usb usb1-port1: cannot reset (err = -32) [ 215.207718] usb usb1-port1: Cannot enable. Maybe the USB cable is bad? [ 215.219317] usb usb1-port1: unable to enumerate USB device Hence we also enable the MXS_PHY_NEED_IP_FIX flag.
