Pull libata fixes from Tejun Heo:

 - 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.
