Teach rfkill about wimax radios.
Had to define a KEY_WIMAX as a 'key for disabling only wimax radios',
as other radio technologies have. This makes sense as hardware has
specific keys for disabling specific radios.
The RFKILL enabling part is, otherwise, a copy and paste of any other
radio technology.

Code inspection turned up that error cases in rfkill_register() do not
call rfkill_led_trigger_unregister() even though we have already

rfkill_toggle_radio is called from functions where
rfkill->mutex is already aquired.
Remove the lock from rfkill_toggle_radio() and add it to
the only calling function that calls it without the lock held.

Replace mutex_lock_interruptible() by mutex_lock() in rfkill_register(),
as interruptible doesn't make sense there.
Add a sanity check for rfkill->type, as that's used for an unchecked dereference
in an array and might cause hard to debug crashes if the driver sets this
to an invalid value.

We must use subsys_initcall, because we must initialize before a

Registering the switch triggers a LED event, so we must register
LED triggers before the switch.
This has a potential to fix a crash, depending on how the device
driver initializes the rfkill data structure.

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

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.
