sunxi: Add CHIP support

Browse Source 
The C.H.I.P. is a small SBC with an Allwinner R8, 8GB of NAND, 512MB of
RAM, USB host and OTG, a wifi / bluetooth combo chip, an audio/video jack
and two connectors to plug additional boards on top of it.

The DT is identical to the DT submitted to the upstream kernel.
