driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

This patch adds state machine for uacce and QM. Related state machine and
lock design documents can be found:

https://github.com/hisilicon/dev-docs/blob/master/warpdrive/state_model.rst
https://github.com/hisilicon/dev-docs/blob/master/warpdrive/uacce_lock.rst

This patch also solves below problems:

- Remove uacce_queue pool in uacce, let's low level driver to maintain
queue pool. So locks(uacce_mutex, uacce->q_lock) for uacce are also
removed.

- Provide an ioctl to put hardware queue, as hardware queue which is put in
uacce .release callback will be delayed to put in kernel.

- Modify reset logic of uacce. UACCE_ST_RST state of uacce has been
deleted. Current logic is: before doing hardware reset, a SIGIO has been
sent to process which has been binded with uacce_queue, low level driver
waits user to close all fds before doing uacce_unregister; after hardware
reset done, low level driver can register to uacce subsystem again.

- Modify the way to send reset signal: use send_sig_info to send signal.

Known issue as comments of function uacce_send_sig_to_client:

"This function can be called in low level driver, which may bring a race
with uacce_fops_release. The problem is this function may be called
when q is NULL. Low level driver should avoid this by locking hardware
queue pool and check if there is related hardware queue before calling
this function.

Modify the sec/rde module codes to adapt the uacce/qm changes.
