touchscreen: use repeat acceleration for button input

Browse source 
Touch devices have physical buttons too, and these should be
subject to repeat acceleration. That feature was disabled for
the sake of better touch event responsiveness (apparently).

So, re-enable the acceleration feature & add a special case
to exempt BUTTON_TOUCHSCREEN from acceleration.
