dell-wmi: enable receiving WMI events on Dell Vostro V131
On some laptop models (e.g. Dell Vostro V131), WMI events are not generated until a specific SMBIOS request is issued to register an event listener [1]. As there seems to be no ACPI method or SMBIOS request to determine without possible side effects whether a given machine needs to issue this SMBIOS request in order to receive WMI events, DMI matching is used to whitelist the models which need it.

Say Y here if you want to support WMI-based hotkeys on Dell laptops.
