thunderbolt: Configure link after lane bonding is enabled
During testing it was noticed that the link is not properly restored after the domain exits sleep if the link configured bits are set before lane bonding is enabled. The USB4 spec does not say in which order these need to be set but setting link configured afterwards makes the link restoration work so we do that instead.
