notifier: Add atomic_notifier_call_chain_is_empty()
Add atomic_notifier_call_chain_is_empty() that returns true if given
atomic call chain is empty.
The first user of this new notifier API function will be the kernel
power-off core code that will support power-off call chains. The core
code will need to check whether there is a power-off handler registered
at all in order to decide whether to halt machine or power it off.
