I don't think Google is working on it. Intel and AMD have some comments on the relevant issue[1].
As far as I can see there seems to be a lot of noise ("How do I run Caffe on OpenCL") and not huge amounts of progress.
The truth is that you are better off waiting for external NVidia GPUs[2] to become widely available[3] than waiting for a decent OpenCL implementation.
