[PATCH 4/4] [DO NOT MERGE] ARM: dts: sun8i: Add CAM500B camera module to the Nano Pi M1+

[Maxime Ripard <maxime.ripard@xxxxxxxxxxx>]

From: Mylène Josserand <mylene.josserand@xxxxxxxxxxx>

The Nano Pi M1+ comes with an optional sensor based on the ov5640 from
Omnivision. Enable the support for it in the DT.
