Subject: ACPI / blacklist: add _REV quirks for Dell Precision 5520 and 3520

ACPI / blacklist: add _REV quirks for Dell Precision 5520 and 3520

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.
