From: Biju Das <biju.das.jz@bp.renesas.com>
RZ/G3L SMARC EVK has 3 user buttons called USER_SW1, USER_SW2 and USER_SW3. Instantiate the gpio-keys driver for these buttons by removing place holders and replacing proper pins for the buttons.
The USER_SW{1,2,3} configured as wakeup-source, so it can wakeup the system during s2idle.
