x86, mtrr: Use pci_dev->revision

Browse Source 
This code uses PCI_CLASS_REVISION instead of PCI_REVISION_ID, so
it wasn't converted by commit 44c10138fd ("PCI: Change all
drivers to use pci_device->revision") before being moved to
arch/x86/...

Do it now at last -- and save one level of indentation...
