remove a segment of code, in which it forces EHCI to be connected firstly before UHCI when ConOut variable contains such usb device path.
This code was used to tune performance in Edk. Due to EdkII has enhanced Ehci driver to force it to be connected before UHCI, then the same logic is not necessary.
