For some user cases, like plug out and replug in usb device during the system suspend, the speed negotiation will be error due to host doesn't know the device's disconnection, and it still hopes the high speed device, but the device backs to "powered" state which its high speed termination is not enabled, the usb core calls the PHY's disconnect notifier with "full speed", it will NOT take effect at all. If the usb core calls disconnect notifer, the port change must happen, so it is safe to disable high speed disconenct detector, since connect notifier will be called soon if the device is still connected on the port, and we will enable high speed disconnect detector at that time.

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.

When we need the PHY can be waken up by external signals, we can call this API. Besides, we call mxs_phy_disconnect_line at this API to close the connection between USB PHY and controller, after that, the line state from controller is SE0. Once the PHY is out of power, without calling mxs_phy_disconnect_line, there are unknown wakeups due to dp/dm floating at device mode.
