gpu: nvgpu: add profiler apis for resource reservation

Browse Source 
Add two new functions to reserve/release PM resources :
nvgpu_prof_ioctl_reserve_pm_resource()
nvgpu_prof_ioctl_release_pm_resource()

Add ctxsw field to struct nvgpu_profiler_object to store per-resource
context switch enable flag.

Force resource reservation release while unbinding the context from
profiler object or while closing the profiler object. Add this code
in nvgpu_profiler_unbind_context() since both above paths will call
this function.
