HID: hid-magicmouse: Correct touch orientation direction
commit 2d9ca4e9f393d81d8f37ed37505aecbf3a5e1bd6 upstream. 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.
