Bhaktipriya Shridhar 7166829215 fbdev: Remove deprecated create_singlethread_workqueue
The workqueue "esd_wq" has only a single workitem(&md->esd_work)
and hence doesn't require ordering. Also, it is not being used on a
memory reclaim path. Hence, the singlethreaded workqueue has been
replaced with the use of system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_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
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

mipid_esd_stop_check () calls cancel_delayed_work() in mipid_cleanup()
to ensure that there are no pending tasks while disconnecting the driver.
