[PATCH 3/3] ARM: dts: sun7i: lamobo-r1: Add backup battery charging property

[Paul Kocialkowski]

This adds the axp20x backup property to the lamobo-r1 device-tree,
that allows charging the backup battery attached to its AXP209.

It is especially useful since the battery is used for the RTC module.
