platform/x86: wmi: Remove ACPI handlers after WMI devices
When removing the ACPI notify/address space handlers, the WMI devices
are still active and might still depend on ACPI EC access or
WMI events.
Fix this by removing the ACPI handlers after all WMI devices
associated with an ACPI device have been removed.
