Subject: [PATCH] testevdev: Try to correct Wii devices guessed from kernel
 source

The comments here disagreed with the actual bytes. According to
https://elixir.bootlin.com/linux/v6.3.7/source/drivers/hid/hid-wiimote-modules.c,
the Balance Board reports BTN_A and ABS_HAT0X, HAT0Y, HAT1X and HAT1Y.
This means the comments here were correct, but the .abs bits shown
were in the wrong byte.

Matching the Wii U Pro Controller against the same kernel source, it
appears to be correct: it's the same representation as a PS3 gamepad,
except that it lacks the Z and RZ axes for analogue triggers.
