[PATCH v3 4/6] drm/amdgpu: UAPI headers for userqueue Secure semaphore

[Arunpravin Paneer Selvam <Arunpravin.PaneerSelvam@xxxxxxx>]

 - Add UAPI header support for userqueue Secure semaphore

   v2: Worked on review comments from Christian for the
       following modifications

       - Add bo handles, bo flags and padding fields.
       - Include value/va in a combined array.

   v3: Worked on review comments from Christian

       - Fix padding issues
       - Add a number variable (num_fences) to get how much
         space we need to allocate for userq_fence_info
       - Write better name for the variables
