Patch works to me for avoid DVD detection on Intel Shark Bay development
machine.

    Also, are you sure this one and the following Lynx Point controllers are 
not affected?

There is a quirk patch 5e5a4f5d5a08c9c504fe956391ac3dae2c66556d fix the 4 ports
IDE controller 32bit PIO mode. 
Recently, the problem was showed at Haswell platform which includes 2 ports 
IDE controller.

So introduce a qurik patch to disable 32bit PIO at this IDE controller.

I am not sure. the 0x8c09 is possibly used on mobile PC not desktop. On
one of my machine, it includes the chipset but the 2 ports IDE controller is
not extend out for use. There are only 2 ports extended out from 4 ports
IDE controller.  So I can not verify it. I think, the notebook/mobile PC does
 not require to extends out all of the IDE ports. 

This patch only fixs the 0x8c08 2 ports IDE controller for it block the
installation. If there is an issue reporting from 0x8c09, we can fix it
late.

Thanks

There is a quirk patch 5e5a4f5d5a08c9c504fe956391ac3dae2c66556d fix the 4 ports
IDE controller 32bit PIO mode. 
Recently, the problem was showed at Haswell platform which includes 2 ports 
IDE controller.

So introduce a qurik patch to disable 32bit PIO at this IDE controller.
