[PATCH] ARM: dts: BCM5301X: add missing LEDs for Buffalo WZR-900DHP

[musashino.open at gmail.com]

From: INAGAKI Hiroshi <musashino.open@gmail.com>

Buffalo WZR-900DHP has 8 LEDs, but there is not LED definitions in the
dts and cannot configure these LEDs.
I Added missing LED definitions for WZR-900DHP.

Looks almost good, thanks for sending this patch to Florian.

One comment: please drop all linux,default-trigger = "default-off";
lines. I did the same mistake long time ago, see my fixing commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0b660259e927177dc0c6eb3b1c39f23c6a011c5f

When you fix that, please generate a V2 of your patch, you can do it
with something like:
git format-patch --subject-prefix="PATCH V2" -1
and send again the same way.

Thanks!
