In DP simulation mode, DP link clock's parent is driven by usb pll clock, in case usb is disconnected during DP simulation, those registers driven by DP link clock cannot be accessed any more. In that case, put xo clock as DP link clock's parent to keep the registers driven by link clock still be accessible.
