usb: usb251xb: Add 5,6,7 ports boost settings
USB electrical signaling drive strength boost bit is also supported by USB2517 hub. Since it got three addition ports, the designers needed to add one more register for initialization. It turned out to be formerly reserved 0xF7. As before we just initialize it with default zeros.
