Created a thread using alloc_ordered_workqueue() API in order to process
the works from firmware Work-queue sequentially instead of
create_singlethread_workqueue() API.

Changes in v1:
    No need to check for backport compatibility in the upstream kernel.
so removing the else section where driver use
create_singlethread_workqueue() API if alloc_ordered_workqueue() API is
not defined, This else section is not required since in the latest upstream
kernel this alloc_ordered_workqueue() API is always defined.

Changes in v2:
	Patch version change only.
