Deepak Nibade e4e6be85ea gpu: nvgpu: move profiler alloc/free APIs to separate file ...

Move profiler object allocation/free APIs to separate profiler
specific file common/profiler.c.

Store struct gk20a pointer in struct dbg_profiler_object_data for
convenience of accessing global struct pointer.

Update profiler object to store TSG pointer instead of channel
pointer. Since expectations is to have one profiler object
per context/TSG.

nvgpu_profiler_reserve_acquire() has a case to check if resource
reservation is acquired by some other channel in TSG.
But now since we keep track of TSG itself, this case becomes
redundant and can be removed.

All the support is compiled out of safety build with compile
flag CONFIG_NVGPU_PROFILER.
Linux will always compile the support.
