----------------------------------------------------------------------

During hisilicon accelerator live migration operation. In order to
prevent the problem of EQ/AEQ interrupt loss. Migration driver will
trigger an EQ/AEQ doorbell at the end of the migration.

This operation may cause double interruption of EQ/AEQ events.
To ensure that the EQ/AEQ interrupt processing function is normal.
The interrupt handling functionality of EQ/AEQ needs to be updated.
Used to handle repeated interrupts event.
