platform/x86: wmi: Do not instantiate older WMI drivers multiple times
Many older WMI drivers cannot be instantiated multiple times for
two reasons:

- they are using the legacy GUID-based WMI API
- they are singletons (with global state)

Prevent such WMI drivers from binding to WMI devices with a duplicated
GUID, as this would mean that the WMI driver will be instantiated at
least two times (one for the original GUID and one for the duplicated
GUID).
WMI drivers which can be instantiated multiple times can signal this
by setting a flag inside struct wmi_driver.

Tested on a ASUS Prime B650-Plus.

2340f12023 platform/x86/intel/wmi: thunderbolt: Use bus-based WMI interface
Currently, the driver still uses the legacy GUID-based interface
to invoke WMI methods. Use the modern bus-based interface instead.

Tested on a Lenovo E51-80.

4e3d731ba7 platform/x86/intel/wmi: thunderbolt: Use dev_groups callback
Use .dev_groups callback instead of manual sysfs registration.
Remove .probe and .remove callbacks as they become dummy after
using .dev_groups.
