I really dislike this being open coded in drivers. It really should
be helper chared with the blk-mq map building that drivers just use.
For now just have a low-level blk_pci_map_queues that
blk_mq_pci_map_queues, hpsa and megaraid can share. In the long run
it might make sense to change the blk-mq callout to that low-level
prototype as well.
