lenovo/x60: add GPIOs initialisation before dock check
Add GPIOs initialisation before dock check. Needed in order to properly detect the presence or absence of the lenovo dock. Previously the check always reported the dock as connected and currently it always reports it as disconnected since the GPIOs are not properly initialised during the check. Tested and confirmed working.
