[4/6] ARM: sunxi: Support the Nextthing GR8

The GR8 is an SoC made by Nextthing Co, loosely based on the sun5i family.

It has a number of new controllers compared to the A10s and A13 (SPDIF, I2S),
but some controllers missing too (Ethernet, less I2C, less UARTs).

Please update Documentation/arm/sunxi/README as well. I don't suppose
there's a datasheet available?
