[PATCH 4.9 234/245] ARM: dts: exynos: fix PWM LED max brightness on Odroid XU/XU3

[Greg Kroah-Hartman]

From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxxxxx>

[ Upstream commit 75121e1dc9fe4def41e63d57f6a53749b88006ed ]

There is no "max_brightness" property.  This brings the intentional
brightness reduce of green LED and dtschema checks as well:

  arch/arm/boot/dts/exynos5410-odroidxu.dt.yaml: led-controller-1: led-1: 'max-brightness' is a required property

Fixes: 719f39fec586 ("ARM: dts: exynos5422-odroidxu3: Hook up PWM and use it for LEDs")
