platform/x86: msi-wmi-platform: Only load on MSI devices

Browse source

It turns out that the GUID used by the msi-wmi-platform driver
(ABBC0F60-8EA1-11D1-00A0-C90629100000) is not unique, but was instead
copied from the WIndows Driver Samples. This means that this driver
could load on devices from other manufacturers that also copied this
GUID, potentially causing hardware errors.

Prevent this by only loading on devices whitelisted via DMI. The DMI
matches where taken from the msi-ec driver.
