These patches were part of 'honor isolcpus configuration' [1] series. To
simplify the review process I decided to send this as separate series
because I think it's a nice cleanup independent of the isolcpus feature.

One thing which I am a bit unsure are the CONFIG bits. I've reused the
BLK_MQ_PCI and BLK_MQ_VIRTIO as guard for the new helpers but it looks a
bit off.

changes:
  - renamed blk_mq_dev_map_queues to blk_mq_hctx_map_queues
  - squased 'virito: add APIs for retrieving vq affinity' into
    'blk-mq: introduce blk_mq_hctx_map_queues'
  - moved hisi_sas changed into a new patch
  - hisi_sas use define instead of hard coded value
  - moved helpers into their matching subsystem, removed
    blk-mq-pci and blk-mq-virtio files
  - fix spelling/typos
  - fixed long lines in docu (yep new lines in brief descriptions are
    supported, tested ti)
