scsi: smartpqi: Add driver support for multi-LUN devices
Add driver support for up to 256 LUNs per device.
Update AIO path to pass the appropriate LUN number for base-code to target
the correct LUN.
Update RAID IO path to pass the appropriate LUN number for FW to target the
correct LUN.
Pass the correct LUN number while doing a LUN reset.
Count the outstanding commands based on LUN number. While removing a
Multi-LUN device, wait for all outstanding commands to complete for all
LUNs.
Add Feature bit support.
