ARM: dts: kzm9g: Configure NMI key as wake-up source

Add a GPIO key with wake-up capability for the NMI button. This allows to wake up the system from s2ram without relying on the buttons on the optional switch board. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
