Bhaktipriya Shridhar eac9837f87 spi: spi-bfin-sport: Remove deprecated create_singlethread_workqueue 
The workqueue "workqueue" serves as a driver message queue.
It has a single work item(&drv_data->pump_messages) 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.

Work item has been flushed in bfin_sport_spi_destroy_queue() to ensure
that there are no pending tasks while disconnecting the driver.
