"ata_piix: make DVD Drive recognisable on systems with Intel Sandybridge
chipsets(v2)" fixing the 4 ports IDE controller 32bit PIO mode.

We've hit a problem with DVD not recognized on Haswell Desktop platform which
includes Lynx Point 2-port SATA controller.

This quirk patch disables 32bit PIO on this controller in IDE mode.

v2: Change spelling error in statememnt pointed by Sergei Shtylyov.
v3: Change comment statememnt and spliting line over 80 characters pointed by
Libor Pechacek and also rebase the patch against 3.8-rc7 kernel.
