[PATCH] arm64: dts: allwinner: a64: olinuxino: add user red LED

[Petr Štetiar]

There is a red LED marked as `GPIO_LED1` on the silkscreen and connected
to PE17 by default. So lets add this missing bit in the current hardware
description.

The gpio-led binding seems to prefer "led-0" up to "led-f" (^led-[0-9a-f])
as the child node name. This was recently brought to my attention. Do we
want to follow suit here?

I can see following in Documentation/devicetree/bindings/leds/leds-gpio.yaml:

 patternProperties:
   # The first form is preferred, but fall back to just 'led' anywhere in the
   # node name to at least catch some child nodes.
   "(^led-[0-9a-f]$|led)":

So it seems like `led-0` is indeed preferred, should I send v2 or a new patch
as a fix on top of the previous one?
