nvc0: enable compute support on Fermi

Altough the compute support is still not complete because textures and
surfaces need to be implemented, it allows to launch very simple compute
kernel like one which reads reading MP performance counters.

This turns on PIPE_CAP_COMPUTE and PIPE_SHADER_COMPUTE.
