src/drivers/pc80: Remove empty struct keyboard

This is a empty struct that has propagated through the superio's & ec's
but really does nothing. Time to get rid of it before it adds yet more
cruft. However, since this touches many superio's at once we do this in
stages by first changing the function type to be a pure procedure.
