[ Upstream commit5acab6eb59] 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.
