Merge "Allwinner device tree changes for 3.20" from Maxime Ripard:

A lot of changes to the device tree for the 3.20 merge window, mostly with:
  - More DT license convertions, only two DTS and two DTSI are still uncertain
    and have not been converted yet
  - Use the C-preprocessor includes in the device trees.
  - Add support for the A31s SoC and improve the A80 support
  - Add IR receiver, lradc, PS/2 support
  - Add cpufreq support for all SoCs but the A23 and A80.
  - And a lot of new boards
