crypto: hisilicon/qm - allow VF devices to query hardware isolation status

The problem that the VF device cannot obtain the isolation
status and isolation threshold of the device is resolved.

The accelerator driver can query the device isolation status
and threshold via the VF device using the fault query sysfs
interface under uacce. Note that only the PF device supports
isolation policy configuration, while the VF device is
limited to read-only query operations.
