scsi: pm80xx: Add sysfs attribute to track iop0 count
A new sysfs variable 'ctl_iop0_count' is being introduced that tells if
the controller is alive by indicating controller ticks. If on subsequent
run we see the ticks changing that indicates that controller is not
dead.
Using the 'ctl_iop0_count' sysfs variable we can see ticks incrementing:
linux-9saw:~# cat /sys/class/scsi_host/host*/ctl_iop0_count
0x000000a3
0x000001db
0x000001e4
0x000001e7
