scsi: hisi_sas: Add poll support for v3 hw
Add a module parameter to set how many queues are used for iopoll. Also
fill the interface mq_poll. For internal I/Os from libsas and libata we use
non-iopoll queue (queue 0) to deliver and complete them. But for internal
abort I/Os, just don't send them for poll queues.
There is still a risk associated as this sends internal abort commands to
non-iopoll queues which actually requires sending an internal abort command
to every queue. As a result, make the module parameter as "experimental"
for now.
