Following two patches enable Mali400 GPU on Allwinner R40 SoC. At this point I didn't add table for frequency switching because it would require far more testing and defaults work stable and reasonably well.
Please take a look.
Best regards, Jernej

Allwinner R40 SoC contains Mali400, so add its specific compatible to bindings.
