drm/radeon: Remove deprecated create_singlethread_workqueue
alloc_workqueue replaces deprecated create_singlethread_workqueue().
Each hardware CRTC has a single flip work queue.
When a radeon_flip_work_func item is queued, it needs to be executed
ASAP because even a slight delay may cause the flip to be delayed by
one refresh cycle.
Hence, a dedicated workqueue with WQ_HIGHPRI set, has been used here
since a delay can cause the outcome to miss the refresh cycle.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary here.
