for Hi1620 hardware, we should disable these hardware flr:
1. BME_FLR - bit 7,
2. PM_FLR - bit 11,
3. SRIOV_FLR - bit 12,
Or HPRE may goto D3 state, when we bind and unbind HPRE quickly,
as it does FLR triggered by BME/PM/SRIOV.

As before, if a SEC queue is at the 'fake busy' status,
the request with a 'fake busy' flag will be sent into hardware
and the sending function returns busy. After the request is
finished, SEC driver's call back will identify the 'fake busy' flag,
and notifies the user that hardware is not busy now by calling
user's call back function.
Now, a request sent into busy hardware will be cached in the
SEC queue's backlog, return '-EBUSY' to user.
After the request being finished, the cached requests will
be processed in the call back function. to notify the
corresponding user that SEC queue can process more requests.

we found that SEC only supports two threads each with one TFM
based on the default module parameter 'ctx_q_num'.
If running more threads, stress-ng will fail since it cannot

In order to fix this, we adjusted the default values
