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. 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.
