[PATCH V3 1/1] ARM: dts: imx6qdl-sabrelite: add gpio-keys

[Troy Kisky]

Add power, menu, home, back, volume up, and volume down
buttons.

Also, apply same changes to imx6qdl-nitrogen6x.

Signed-off-by: Troy Kisky <troy.kisky at boundarydevices.com>

v3: add pinctrl_gpio_keys, make same changes to
imx6qdl-nitrogen6x.dtsi

v2: add #include <dt-bindings/input/input.h>
to substitute KEY_POWER for 116
