Making a reference to the common work queue code should not necessarily drag in the system workqueue, since it is possible to use a workqueue that is not the system workqueue. This is done by moving the system workqueue into its own code module. Moving the system workqueue to its own code module allows removing the NANO_WORKQUEUE and SYSTEM_WORKQUEUE kconfig options, and compiling the common workqueue code and system workqueue all the time. They are only linked in the final image if a reference to them exist, same as the other kernel modules.
