[PATCH v1] ARM: dts: rockchip: Update LEDs to work with the last leds-gpio driver on radxarock

See https://www.kernel.org/doc/Documentation/leds/leds-class.txt for
LEDs device naming

> The leds-gpio driver recently switched to the device property API. The device_node
> name is no longer retrieved if the "label" devicetree property is not found.
> In this case the driver tries to create entries with (null) name in
> /sys/class/leds, which is wrong and generates backtrace as several gpio_leds have
> the same name. Also renamed subnode "yellow" to "blue" to match the last
> schematics updates.
