arm64: dts: renesas: r9a08g046l48-smarc: Add gpio keys

Browse Source 
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.

USER_SW{1,2,3} are configured as wakeup-sources, so they can wake up the
system during s2idle.
