scsi: pm80xx: Add sysfs attribute to check controller hmi error
A new sysfs variable 'ctl_hmi_error' is being introduced to give the error
details if the MPI initialization fails
Using the 'ctl_hmi_error' sysfs variable we can check the error details:
linux-2dq0:~# cat /sys/class/scsi_host/host*/ctl_hmi_error
0x00000000
0x00000000
0x00000000
