rfkill: Move "state" sysfs file back to stable 



There is still quite a bit of code using this interface, so we can't
just remove it. Hopefully it will be possible in the future, but since
its scheduled removal date is past 2 years already, we are better having
the documentation reflecting the current state of things.

Description: 	Current state of the transmitter.

		This file is deprecated and scheduled to be removed in 2014,

		because its not possible to express the 'soft and hard block'

		state of the rfkill driver.

Values: 	A numeric value.

		0: RFKILL_STATE_SOFT_BLOCKED

			transmitter is turned off by software

		1: RFKILL_STATE_UNBLOCKED

			transmitter is (potentially) active

Description: 	Current state of the transmitter.

		This file was scheduled to be removed in 2014, but due to its

		large number of users it will be sticking around for a bit

		longer. Despite it being marked as stabe, the newer "hard" and

		"soft" interfaces should be preffered, since it is not possible

		to express the 'soft and hard block' state of the rfkill driver

		through this interface. There will likely be another attempt to

		remove it in the future.
