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.

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.
