Buttons that work directly on hardware cannot support
the "user_claim" functionality. Add a flag to signal
this and return -EOPNOTSUPP in this case.
b43 is such a device.

rfkill_switch_all shouldn't be called by drivers directly,
instead they should send a signal over the input device.

To prevent confusion for driver developers, move the
function into a rfkill private header.

As Dmitry pointed out earlier, rfkill-input.c
doesn't support irda because there are no users
and we shouldn't add unrequired KEY_ defines.

However, RFKILL_TYPE_IRDA was defined in the
rfkill.h header file and would confuse people
about whether it is implemented or not.

This patch removes IRDA support completely,
so it can be added whenever a driver wants the
feature.

we already pass the argument for the store handler,
so we only need to update the permissions flag.
