David Nieto 74fe1caa2b gpu: nvgpu: Add refcounting to driver fds ...

The main driver structure is not refcounted properly,
so when the driver unload, file desciptors associated to the
driver are kept open with dangling references to the main object.

This change adds referencing to the gk20a structure.
