The EliteDesk 800 G6 stores a raw WMI string within the ACPI object in its
BIOS corresponding to one instance of HPBIOS_PlatformEvents.Name. This is
evidently a valid way of representing a WMI data item as far as the Microsoft
ACPI-WMI mapper is concerned, but is preventing the driver from loading.
As this seems quite rare, add a machine-limited workaround for now.

Would it be possible to use a dmi table and dmi_check_system() ?
That would make it easier to add more platforms later on if needed.
