lenovo/t60: Enable dock serial port when undocked and redocked

When the system is started with dock, the serial port works.
    As soon as the laptop is undocked and redocked, the serial port
    no longer works.  See below superiotool dump snippet:

Upon bootup: SIO @ 0x2e
    LDN 0x03 (COM1)
    idx 30 60 61 70 71 74 75 f0
    val 01 03 f8 04 03 04 04 02

Redocked:    SIO @ 0x2e
    LDN 0x03 (COM1)
    idx 30 60 61 70 71 74 75 f0
    val 00 03 f8 04 03 04 04 02

Since the function dock_connect is executed every time the
    dock is reconnected, starting without a dock and then attaching
    it to a dock is now also fixed.
