2fb3c5d0d1 drm/amdgpu: change psp_rap_invoke() function return value 
RAP TA is an optional firmware. if it doesn’t exist,
the driver should bypass psp_rap_invoke() function.

1. bypass psp_rap_invoke() when RAP TA is not loaded.
2. add new parameter (status) to query RAP TA status.
   (the status value is different with psp_ta_invoke(),
3. fix the 'rap_status' MThread critical problem.
   (used without lock)

a4322e1881 drm/amdgpu: add debugfs interface for RAP test 
After amdgpu driver loading successfully, we can use
RAP debugfs interface <debugfs_dir>/dri/xxx/rap_test
to trigger RAP test.

Currently only L0 validate test is supported.
