[PATCH 4.4 72/76] ACPI / blacklist: add _REV quirks for Dell Precision 5520 and 3520

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 9523b9bf6dceef6b0215e90b2348cd646597f796 ]

Precision 5520 and 3520 either hang at login and during suspend or reboot.

It turns out that that adding them to acpi_rev_dmi_table[] helps to work
around those issues.
