This adds a device tree usable on Mele A1000 (and A2000, as it
apparently is the same device except for the case). This device features
one UART port, Ethernet, an AXP209 PMU on i2c0 and two user configurable
LEDs.

Maxime, this v2 should address all your comments.

Cheers,

Emilio

Applied with a minor fix to the soc node address on my sunxi/dt-for-3.12
branch.

Thanks,
Maxime
