I don't have any strong opinion here. I wasn't convinced by any of my
ideas when I committed this.

It looks like most OpenCL machines will have multiple platforms (one for
CPU and one for GPU/accelerator) so we have to always keep the platform
in the name. I'll be ok with whichever of XpY or YdX or pYdX or anything
better.

Ideally, we could even have a OS device for each OpenCL platform, each
containing OS devices for devices of the platform. But I'd rather keep a
single level to match other OS devices.
