alloc_ordered_workqueue() with WQ_MEM_RECLAIM set, replaces
deprecated create_singlethread_workqueue(). This is the identity
conversion. The workqueue "ts_workq" has been identity converted.
It queues work items viz &wm->ts_reader and &wm->pen_event_work which map
to wm97xx_pen_irq_worker (handles a pen down interrupt) and
wm97xx_ts_reader (the touchscreen sample reader) respectively. Hence,
an ordered dedicated workqueue has been used.
WQ_MEM_RECLAIM has been set to ensure forward progress under memory
pressure.
