The magic trackpad and mouse both report touch orientation in opposite
direction to the bcm5974 driver and what is written in
Documents/input/multi-touch-protocol.txt. This patch reverts the
direction, so that all in-kernel devices with this feature behave the
same way.

Since no known application has been utilizing this information yet, it
seems appropriate also for stable.
