Subject: [PATCH 1/1] add mali r6p2 dt node

It seems there is not mali node in sun7i-a20.dtsi

Add mali node to sun7i-a20.dtsi

This patch adds device tree mali node compatible with r6p2 utgard kernel driver 
provided by ARM and patched by maxime ripard on his github.

It can be easily used in target.dts with:

&mali {
	status = "okay";
}

then loading mali.ko in user space.
