sunxi: Sync dts files with the linux kernel
Copy over all the latest dts changes from mripard/sunxi/dt-for-4.2 ,
this gives us a proper dtsi file for the A33 rather then abusing
sun8i-a23.dtsi for this.
And this replaces our minimal (dummy) sun7i-a20-mk808c and
sun8i-a33-astar-mid756 dts files with proper ones.
