[PATCH] ACPI: Override rev for DELL Latitude 3350

[AceLan Kao]

The ethernet network fails to work on DELL Latitude 3350 after this commit
   ea7d521 Revert 'Revert "ACPICA: Permanently set _REV to the value '2'."'

dmesg shows
   r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
   r8169 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control
   pci 0000:00:1c.2: PCI INT C: failed to register GSI
   pci 0000:00:1c.2: Error enabling bridge (-16), continuing
   r8169 0000:03:00.0: PCI INT A: failed to register GSI
   r8169 0000:03:00.0 (unnamed net_device) (uninitialized): enable failure
   r8169: probe of 0000:03:00.0 failed with error -16

So override the ACPI _REV for this machine to fix the issue.
