platform/x86: wmi: Mark simple WMI drivers as legacy-free

The inspur_platform_profile driver and the xiaomi-wmi driver both
meet the requirements for modern WMI drivers, as they both do not
use the legacy GUID-based interface and can be safely instantiated
multiple times.

Mark them both as legacy-free using the no_singleton flag.

Compile-tested only.
