Destage the VCHIQ interface driver to drivers/platform/raspberrypi. There is still the remaining TODO item of improving the documentation, which can be handled post destaging. Secondly, multimedia drivers like codec and ISP that rely on this interface need to be upstreamed. And lastly, the drivers that facilitate the shared memory between VideoCore and Linux, like the vc-sm-cma driver and vc_mem char driver also need to be upstreamed.
