[GIT PULL] libata fixes for v4.5-rc3

[Tejun Heo]

Hello, Linus.

libata fixes for v4.5-rc3.

* PORTS_IMPL workaround for very early ahci controllers is misbehaving
  on new systems.  Disabled on recent ahci versions.

* Old-style PIO state machine had a horrible locking problem.  Don't
  know how we've been getting away this far.  Fixed.

* Other device specific updates.

Thanks.
