Subject: [PATCH v2 7/8] ARM: dts: sun7i: Enable AXP209 CHGLED for Olimex boards

Olimex A20-OLinuXino based boards (MICRO, SOM, SOM204, LIME2)
commes with populated LED connected to AXP209.

By default the LED is controlled by AXP209, so this binding
actually doesn't modify any registers. However this can can be
used as general purpose LED, if the control mode is overridden.

Also this binding is enabled only for OLIMEX boards, since I have
no knowlegde if the other manifactures are populating this LED.
