Subject: SATA: Add PCI-ID
From: "Adam Helms" <helms.adam@xxxxxxxxx>
Makes the AHCI driver detect the PCI ID 8086:27c0 (IDE interface: Intel
Corporation 82801GB/GR/GH (ICH7 Family) Serial ATA Storage Controller IDE
(rev 01)) as an AHCI chipset.
8086:27c0 also works with ata_piix but it's much slower. 8086:27c0 is
shipped with - among others - new HP Proliant servers.

This patch needs discussing with Intel.
0x27c0 was intentionally omitted, because it is only supposed to show up
when the device is configured into IDE mode.
If the user (read: BIOS) has chosen to configure the device in AHCI
mode, it should show up as a different PCI ID, which ahci.c already
contains.
I'm inclined to NAK the patch, since things appear to be working as
expected.
