The Dell Latitude 3350's ethernet card attempts to use a reserved IRQ (18),
resulting in ACPI being unable to enable the ethernet.
This patch forces a specific _REV (ACPI revision) value as a workaround
to allow the Dell Latitude 3350's board to work correctly.
The approach is similar to 18d78b64fddc11eb336f01e46ad3303a3f55d039
