crypto: hisilicon - qm updates BAR configuration
On new platforms greater than QM_HW_V3, the configuration region for the
live migration function of the accelerator device is no longer
placed in the VF, but is instead placed in the PF.
Therefore, the configuration region of the live migration function
needs to be opened when the QM driver is loaded. When the QM driver
is uninstalled, the driver needs to clear this configuration.
