Moga pivot/universal driver support and issues

[roswell108]

I completely forgot I posted this. The controls.ini should be in the sdcard PSP/System folder, at least it was last time I needed to modify it.

I also posted to the Github issue, but the "real" fix without forcing mapping is to verify motion on the MotionEvent and if there is none, pass it to the Dpad instead:
