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).
