 numbering for LED triggers

Hi Chen-Yu Tsai,

The led node names need some changes.
'linux,default-trigger' value does not fit.

>From 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)":
    type: object

Rename led nodenames to 'led-0' form

Also include all mail lists found with:
./scripts/get_maintainer.pl --nogit-fallback --nogit

devicetree@...r.kernel.org

If you like change the rest of dts with leds as well...
