[PATCH] piix: Support 6300ESB SATA DMA adapter

[Joshua Kwan]

Hello,

It turns out that the piix IDE driver works for PCI ID 8086:25a3
(PCI_DEVICE_ID_INTEL_ESB_3) as well, per http://bugs.debian.org/254748,
so this patch allows piix to recognize it automatically. Darik Horn
originally wrote this patch.

Marcelo, please apply.
