ACPI: event: Redefine acpi_notifier_call_chain()
Notice that acpi_notifier_call_chain() only uses its device argument
to retrieve the pnp.device_class and pnp.bus_id values from there, so
it can be redefined to take pointers to those two strings as parameters
istead of a struct acpi_device pointer.
That allows all of its callers to pass a string literal as its first
argument, so they won't need to initialize pnp.device_class in
struct acpi_device objects operated by them any more, and its
signature becomes more similar to acpi_bus_generate_netlink_event()
then.
Update the code as per the above.
No intentional functional impact.
