Allwinner DRM driver for 4.7

This pull request introduces the sun4i driver, meant to be used on the
older Allwinner SoCs (A10, A13, A20, A23, A31 and A33).

It currently supports only the A13, which has one of the simplest video
pipeline. Support for other video components and SoCs will be added
eventually.

It supports only a RGB or composite output. It doesn't do HDMI, VGA, LVDS
or power management yet, but that will come in time as well.
