[GIT PULL] libata fixes for v4.18-rc4

[Tejun Heo <tj@kernel.org>]

Hello, Linus.

* Jens's patches to expand the usable command depth from 31 to 32
  broke sata_fsl due to a subtle command iteration bug.  Fixed by
  introducing explicit iteration helpers and using the correct
  variant.

* On some laptops, enabling LPM by default reportedly led to
  occasional hard hangs.  Blacklist the affected cases.

* Other misc fixes / changes.

Thanks.
