!791 crypto: hisilicon/qm - support dumping stop queue status

Merge Pull Request from: @xiao_jiang_shui 
 
Add debugfs 'dev_state' to query the status of the stop queue.
And the root user can set 'dev_timeout', if task flow fails to be
stopped, the driver waits dev_timeout * 20ms before releasing the queue.
