The default multithread workqueue can cause the same work to be executed concurrently on a different CPUs. This isn't really suitable for clock gating as it might already gated the clock and gating it twice results both host->clk_old and host->ios.clock to be set to 0. To prevent this from happening we use system_nrt_wq instead.
