At present the i8042 driver has its own logic and keymaps. In an effort to unify the code, move it over to use the input library. This changes most of the keycode-processing logic since it is now in that library. The main responsibilities of the driver are now to handle the LEDs, deal with the PS/2 extended keycodes and initialise the the keyboard.
