RZ/G3E SMARC EVK has 3 user buttons called USER_SW1, USER_SW2 and
USER_SW3 and SLEEP button with NMI support. Add a DT node in device tree
to instantiate the gpio-keys driver for these buttons.
The system can enter into STR state by pressing the sleep button and
wakeup from STR is done by pressing power button. The USER_SW{1,2,3}
configured as wakeup-source, so it can wakeup the system during s2idle.
