crypto: hisilicon/qm - define the device isolation strategy
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.
