ath79: split Teltonika RUT955 to support other RUT9xx models
Split device-tree of Teltonika RUT955 into a generic RUT9xx part and a part specific to that version of RUT955 already supported. Also harmonize GPIO and LED names with what is used by the vendor firmware and assign RS485 DTR signal. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
