[PATCH] x86, quirks: use pci_dev->revision

[Sergei Shtylyov <sshtylyov@ru.mvista.com>]

This code uses PCI_CLASS_REVISION instead of PCI_REVISION_ID, so it wasn't
converted by commit 44c10138fd4bbc4b6d6bff0873c24902f2a9da65 (PCI: Change all
drivers to use pci_device->revision) before being moved to arch/x86/...
