This button is unusual. On press it emits scanocde 0xe4, on release
0xe5, and when held for a few seconds it begins emitting 0xea about
twice per second. I chose to handle only the press event in order to
make it behave like the other hotkeys.

Probably the closest thing to the intended function of this button
would be to alternate the display orientation between portrait and
landscape, but since there doesn't appear to be a keycode defined for
that function I went with KEY_PROG2. I'm open to other suggestions
however.
