gpu: nvgpu: remove use of nvgpu_ctxsw_trace_entry

Browse Source 
- Remove the usage of nvgpu_ctxsw_trace_entry splattered
across nvgpu, and replace with a struct defined in common code.
The usage is still inside Linux, but this helps the
subsequent unification efforts, e.g. to unify the fecs trace
path.
- Remove "asm/barrier.h" as "nvgpu/barrier.h" is already
included.
