a66ccfc253 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.

348d9cc7bd platform/x86: intel-wmi-sbl-fw-update: Fix function name in error message 
Since when the driver was converted to use the bus-based WMI
interface, the old GUID-based WMI functions are not used anymore.
Update the error message to avoid confusing users.

Compile-tested only.

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.

75c487fcb6 platform/x86: intel-wmi-sbl-fw-update: Use bus-based WMI interface 
Currently, the driver was still using the deprecated GUID-based
interface to query/set data blocks. Use the modern bus-based
interface for this.

Tested with a custom SSDT from the Intel Slim Bootloader project.

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.
