crypto: hisilicon/qm - obtain stop queue status

The debugfs files 'dev_state' and 'dev_timeout' are added.
Users can query the current queue stop status through these two
files. And set the waiting timeout when the queue is released.

dev_state: if dev_timeout is set, dev_state indicates the status
of stopping the queue. 0 indicates that the queue is stopped
successfully. Other values indicate that the queue stops fail.
If dev_timeout is not set, the value of dev_state is 0;

dev_timeout: if the queue fails to stop, the queue is released
after waiting dev_timeout * 20ms.

crypto: hisilicon/qm - simplify the status of qm

The 'QM_INIT' and 'QM_CLOSE' status of qm and 'QP_INIT'
and 'QP_CLOSE' status of queue are not actually used. Currently,
driver only needs to switch status when the device or queue
is enabled or stopped, Therefore, remove unneeded status to
simplify driver. In addition, rename'QM_START to'QM_WORK' for
ease to understand.
