panfrost: support PIPE_RESOURCE_PARAM_NPLANES query 

While panfrost doesn't support multi-planar formats directly, we might
still import multi-planar BOs through GBM (for example, when doing direct
scanout in weston).

We can support PIPE_RESOURCE_PARAM_NPLANES by simply counting the
planes we have.
