Subject: [PATCH] ACPI: button: Add a DMI quirk for Razer Blade Stealth 13 late 2019 lid-switch

Running evemu-record on the lid switch event shows that the lid reports
the first close but then never reports an open.  This causes systemd to
continuously re-suspend the laptop every 30s.  Resetting the _LID to
open fixes the issue.

v2: Updated the comment to better describe the behavior of ACPI
