[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, 3.0 or 3.1 time, hopefully it can be
merged to 3.1 at least.

Andrew, the SCSI maintainer seem to ignore this patch, maybe you can queue it?
