rfkill: add notifier chains support
Add a notifier chain for use by the rfkill class. This notifier chain signals the following events (more to be added when needed): 1. rfkill: rfkill device state has changed A pointer to the rfkill struct will be passed as a parameter. The notifier message types have been added to include/linux/rfkill.h instead of to include/linux/notifier.h in order to avoid the madness of modifying a header used globally (and that triggers an almost full tree rebuild every time it is touched) with information that is of interest only to code that includes the rfkill.h header.
