[GIT PULL] libata changes for v4.6-rc1

[Tejun Heo]

Hello, Linus.

libata changes for v4.6-rc1.

* ahci grew runtime power management support so that the controller
  can be turned off if no devices are attached.

* sata_via isn't dead yet.  It got hotplug support and more refined
  workaround for certain WD drives.

* Misc cleanups.  There's a merge from for-4.5-fixes to avoid
  confusing conflicts in ahci PCI ID table.

Thanks.
