[PATCH v2 1/2] arm: dts: imx6qdl-vicut1.dtsi: Add backlight-isb node

[David Jander]

On some older hardware models this is needed. It will do no harm if used
with newer models though.

[PATCH v2 2/2] arm: dts: imx6qdl-vicut1.dtsi: Fix node name backlight_led

[David Jander]

This naming error slipped through, so now that a new backlight node has
been added with correct spelling, fix this one also.
