ACPI: battery: Pass battery hook pointer to hook callbacks
Right now, is impossible for battery hook callbacks
to access instance-specific data, forcing most drivers
to provide some sort of global state. This however is
difficult for drivers which can be instantiated multiple
times and/or are hotplug-capable.
Pass a pointer to the battery hook to those callbacks
for usage with container_of().
