platform/x86: firmware_attributes_class: Simplify API
The module core already guarantees that a module can only be unloaded
after all other modules using its symbols have been unloaded.
As it's already the responsibility of the drivers using
firmware_attributes_class to clean up their devices before unloading,
the lifetime of the firmware_attributes_class can be bound to the
lifetime of the module.
This enables the direct usage of firmware_attributes_class from the
drivers, without having to go through the lifecycle functions,
leading to simplifications for both the subsystem and its users.
