[SCSI] hpsa: dial down lockup detection during firmware flash
Dial back the aggressiveness of the controller lockup detection thread. Currently it will declare the controller to be locked up if it goes for 10 seconds with no interrupts and no change in the heartbeat register. Dial back this to 30 seconds with no heartbeat change, and also snoop the ioctl path and if a firmware flash command is detected, dial it back further to 4 minutes until the firmware flash command completes. The reason for this is that during the firmware flash operation, the controller apparently doesn't update the heartbeat register as frequently as it is supposed to, and we can get a false positive.
