Subject: [PATCH v3 1/5] ARM: sunxi: Add R8 support

The R8 is a new Allwinner SoC based on the A13. While both are very
similar, there's still a few differences. Introduce a new compatible to
deal with them.

In order to have a consistent naming, instead of mentionning the allwinner
A series as the machine name, switch to sun4i/sun5i like what is done for
the other families.
