Add my work to Useful Links

Hi, I have been doing work on VideoCore VI for a bare metal system. Your repository is one of the few public things besides Mesa/Linux on V3D on the internet.

You may find my notes on V3D and the shader language interesting.

I hope to organize my notes and code into a separate repository soon.

I bundled Mesa's disassembler and validator into a single dependency-free header file, then wrote an assembler for V3D shaders.

I also wrote a bare-bones simulator for debugging the binning phase of shaders on any platform.

It might be good to add these to the Read Me to help others find more information on V3D.
