[PATCH v10 0/3] crypto: hisilicon - supports device isolation feature

[Kai Ye]

1、Add the uacce hardware error isolation interface. Hardware error 
   thresholds can be configured by sysfs node. User can get the hardware
   isolated state by sysfs node.
2、Defining the isolation strategy for uacce device by uacce sysfs node. 
   If the number of hardware errors exceeds the configured value, the 
   uacce device will not be available in user space.
3、The ACC VF device use the PF device isolation strategy.
   
changes v1->v2:
	- deleted dev_to_uacce api.
	- add vfs node doc. 
	- move uacce->ref to driver.
changes v2->v3:
	- deleted some redundant code.
	- use qm state instead of reference count.
	- add null pointer check.
	- isolate_strategy_read() instead of a copy.
changes v3->v4:
	- modify a comment
changes v4->v5:
	- use bool instead of atomic.
	- isolation frequency instead of isolation command.
changes v5->v6:
	- add is_visible in uacce.
	- add the description of the isolation strategy file node.
changes v6->v7
	- add an example for isolate_strategy in Documentation.
changes v7->v8
	- update the correct date.
changes v8->v9
    - move isolation strategy from qm to uacce.
changes v9->v10
	- Go back to the v8 version of the solution.
	- Modify some code according to suggestions.
