gpu: nvgpu: Wrappers for checking platform type

Add nvgpu_* wrappers for determining if we're running in simulation
or silicon, and if we're running in hypervisor.

The new wrappers require struct gk20a pointer, and gk20a_fence_wait()
did not have access to one. Add struct gk20a pointer as the first
parameter.
