Deepak Nibade 5311132781 gpu: nvgpu: add profiler apis to bind/unbind PM resources
Add new APIs to bind/unbind PM resources to/from profiler objects:
nvgpu_profiler_bind_pm_resources()
nvgpu_profiler_unbind_pm_resources()

Implement support to bind/unbind SMPC/HWPM/HWPM_STREAMOUT in various
functions in common/profiler/profiler.c.

Unbind all the PM resources explicitly in
nvgpu_profiler_unbind_context() while closing the profiler object.

If resources are bound during a resource reservation request,
unbind the resources explicitly before reserving new resource.
It is responsibility of application to bind the PM resources again.
