[PATCH v7] ARM: dts: sun8i: Add leds and switches on Orangepi Plus boards

[Hans de Goede <hdegoede-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>]

From: Krzysztof Adamski <k@japko.eu>

OrangePi Plus board has two leds - green ("pwr") and red ("status")
and two switches ("sw4" and "sw2"). This patch describes them in
devicetree.

Changes in v6 (hdegoede):
-Merge leds and r_leds nodes into one
-Fix led labels to be in <board>:<colour>:<role> form
-Alphabetically sort the added nodes
-Add support for sw2 (this is the small reset-like button)
Changes in v7 (hdegoede):
-Use PL3 / PL4 in the pinctrl node, not PL03 / PL04
