1、Add the uacce hardware error isolation interface.
2、Add related implementation in ACC driver to support uacce interface.
e.g. Defining the isolation strategy for ACC by uacce sysfs node, if
the AER error frequency exceeds the value of setting for a certain
period of time. The device will not be available in user space. The
VF device use the PF device isolation strategy. as well as the
isolation strategy should not be set during device use.
1、deleted dev_to_uacce api.
2、add vfs node doc.
3、move uacce->ref to driver.
1、deleted some redundant code.
2、use qm state instead of reference count.
3、add null pointer check.
4、isolate_strategy_read() instead of a copy.
