keyboard: Add CONFIG_KEYBOARD_SCANCODE_CALLBACK for board-specific hooks.
Many devices may want board-specific keyboard hooks, for example
allowing easter egg (to replace the key_special today), or to provide
dynamic translation. Both can be done by having a callback whenever the
key state is changed (after scancode is found).
The new CONFIG_KEYBOARD_SCANCODE_CALLBACK allows boards to define their
own hook keyboard_scancode_callback so the keystrokes can be either
changed or monitored.
