gpu: host1x: hw: intr_hw: Remove create_workqueue
System workqueues have been able to handle high level of concurrency for a long time now and there's no reason to use dedicated workqueues just to gain concurrency. Since the workqueue host->intr_wq is involved in sync point interrupts, and sync point wait and is not being used on a memory reclaim path, dedicated host->intr_wq has been replaced with the use of system_wq. Unlike a dedicated per-cpu workqueue created with create_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantees unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. cancel_work_sync() has been used in _host1x_free_syncpt_irq() to ensure that no work is pending by the time exit path runs.
