Define the device isolation strategy by the device driver. The
user configures a hardware error threshold value by uacce interface.
If the number of hardware errors exceeds the value of setting error
threshold in one hour. The device will not be available in user space.
The VF device use the PF device isolation strategy. All the hardware
errors are processed by PF driver.

Before hardware V3, hardwares do not provide the feature registers,
driver resolves hardware differences based on the hardware version.
As a result, the driver does not support the new hardware.

Hardware V3 and later versions support to obtain hardware features,
such as power-gating management and doorbell isolation, through
the hardware registers. To be compatible with later hardware versions,
the features of the current device is obtained by reading the
hardware registers instead of the hardware version.

CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d64de9773c18

----------------------------------------------------------------------

When the driver receives an event interrupt, the driver will enable
the event interrupt after handling all completed tasks on the function,
tasks on the function are parsed through only one thread. If the task's
user callback takes time, other tasks on the function will be blocked.

Therefore, the event irq processing is modified as follows:
1. Obtain the ID of the queue that completes the task.
2. Enable event interrupt.
3. Parse the completed tasks in the queue and call the user callback.
Enabling event interrupt in advance can quickly report pending event
interrupts and process tasks in multiple threads.

A new generation of accelerator Kunpeng930 has appeared, and the
corresponding driver needs to be updated to support some new
algorithms of Kunpeng930. To be compatible with Kunpeng920, we
add parameter 'struct hisi_qm *qm' to sec_algs_(un)register to
identify the chip's version.

At present, as HPRE/SEC/ZIP modules' parameter 'pf_q_num' is 1,
kernel CRYPTO test will fail on the algorithms from the modules,
since 'QP' hardware resources are not enough for CRYPTO TFM.
To fix this, the minimum value of 'pf_q_num' should be 2.

When the devices are removed or not existing, the corresponding algorithms
which are registered by 'hisi-zip' driver can't be used.

Move 'hisi_zip_register_to_crypto' from 'hisi_zip_init' to
'hisi_zip_probe'. The algorithms will be registered to crypto only when
there is device bind on the driver. And when the devices are removed,
the algorithms will be unregistered.

In the previous process, the function 'xxx_register_to_crypto' need a lock
and a static variable to judge if the registration is the first time.
Move this action into the function 'hisi_qm_alg_register'. Each device
will call 'hisi_qm_alg_register' to add itself to qm list in probe process
and registering algs when the qm list is empty.

Since the drivers such as HPRE/SEC/ZIP do not implement
'pci_driver.shutdow', a RAS will be triggered at OS rebooting or shutting
down as the hardware device is processing request.
The log looks like this:
	NOTICE:  [NimbusSecNodeType1]:[2372L]This is sec, Base = 0x141800000
	NOTICE:  [NimbusSecHandle]:[2319L] SecIntSt = 0x3
	NOTICE:  [NimbusSecHandle]:[2320L] SecQmIntStatus = 0x2
	NOTICE:  [PrintSecurityType]:[344L] SecurityType is RECOVERABLE!

This patch offers a new API in qm to shutdown devices, and add shutdown
callbacks in ACC driver based on this new API.

So the running devices will be stopped when the OS reboot or shutdown.
