ARM: sunxi: dt: Add device tree for Mele A1000

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.

This has been tested by arokux on #linux-sunxi in Freenode and found to 
work correctly.

That's not quite useful anymore now that we have a DT-aware bootloader,
I'd remove it.

Why using the hog pins here? I don't think you require it anymore, just
grab the pinctrl node from the regulator, it should work, right?

Do you really need the extra 10 mA here?
