sidk_s5jt200: remove unused code lines
board_button_irq() and board_button_handler() are not in use, as
there is no Kconfig entry that enables them. Let's remove them. We can
add it later when we need it again.

- * Button support.
- *
- * Description:
- * board_button_initialize() must be called to initialize button resources.
- * After that, board_buttons() may be called to collect the current state
- * of all buttons or board_button_irq() may be called to register button
- * interrupt handlers.
- *
- * After board_button_initialize() has been called, board_buttons() may be
- * called to collect the state of all buttons. board_buttons() returns an
- * 8-bit bit set with each bit associated with a button. See the
- * BUTTON_*_BIT definitions in board.h for the meaning of each bit.
- *
- * board_button_irq() may be called to register an interrupt handler that
- * will be called when a button is depressed or released. The ID value is
- * a button enumeration value that uniquely identifies a button resource.
- * See the BUTTON_* definitions in board.h for the meaning of enumeration
- * value. The previous interrupt handler address is returned (so that it
- * may restored, if so desired).
