rt2x00: rt2800lib: turn on tertiary PAs/LNAs for 3T/3R devices
The 3T/3R devices are using the tertiary PAs/LNAs however those are never turned on. Fix the code to turn on those on for such devices. Also modify the code to use switch statements to improve readability. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Signed-off-by: John W.
