1、Add the uacce hardware error isolation interface. Supports
   configures the hardware error isolation frequency.
2、Defining the isolation strategy for ACC by uacce sysfs node. If the 
   number of hardware errors in a per hour exceeds the configured value,
   the device will not be available in user space. The 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.
