This is third part of the Online Controller Reset. In ISR routine, if driver receive the FW state change interrupt
And the online controller reset support enabled in FW, driver will read the controller register. Driver will issue
Controller reset if the FW register state failure. Also driver will back up the pending cmds for the re-fire after
the reset finished.
Also Driver added the CTIO support to this patch.
