Some of the thermal throttle data structures and code are really very intermingled with the sleep (power) control code. They really do belong together in a way since the thermal throttle code uses powersaving to achieve its goal, but it's making it hard to work on the powersave code. Split this up to make that easier. I've also changed the antenna defines to an enum and used the same enum for RX and TX.
