ACPI / blacklist: Make Dell Latitude 3350 ethernet work

From: Michael Pobega <mpobega@neverware.com>

[ Upstream commit 708f5dcc21ae9b35f395865fc154b0105baf4de4 ]

The Dell Latitude 3350's ethernet card attempts to use a reserved
IRQ (18), resulting in ACPI being unable to enable the ethernet.

Adding it to acpi_rev_dmi_table[] helps to work around this problem.
