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.
