libata: ATA_PIIX missing ICH8M PCIIDs.

Hi,

I got a new laptop and I had a little problem that the DVD drive wasn't recognized by
libata's piix driver (but the old IDE Subsystem found it!).

So, after adding the new pciid 8086:2850 it works!
But, I don't know if it's ich_pata_100 or ich_pata_133 since the 
dvd/cd drives only goes up to udma2 speeds.

Thanks,
        Chr.

(I'm not on the list, please keep the cc!)

this patch adds a necessary PCIID for santa rosa's PATA controller.
