A new sysfs variable 'ctl_raae_count' is being introduced that tells if the
controller is alive by indicating controller ticks. If on subsequent run we
see the ticks changing in RAAE count that indicates that controller is not
dead.
Using the 'ctl_raae_count' sysfs variable we can see ticks incrementing:
linux-9saw:~# cat /sys/class/scsi_host/host*/ctl_raae_count
0x00002245
0x00002253
0x0000225e
