[PATCH resend] atp870u: use pci_dev->revision

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

This driver 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).

This patch wasn't merged in either 2.6.39 or 3.0 time, hopefully it can be
merged to 3.1 at least...
