locking/mutex: Introduce mutex_init_with_key()

The following pattern occurs 5 times in kernel drivers:

	lockdep_register_key(key);
	__mutex_init(mutex, name, key);

In several cases the 'name' argument matches #mutex. Hence, introduce
the mutex_init_with_key() macro. This macro derives the 'name' argument
from the 'mutex' argument.
