[PATCH 129/207] drm/amdgpu/mes: update mes fw api

[Alex Deucher <alexdeucher@gmail.com>]

From: Le Ma <le.ma@amd.com>

Update mes_api_def.h to match the latest mes fw.

v2: clean up coding style based on kernel standards:
  - fix indentation and alignment
  - break long lines
  - put the opening brace last on the line
  - remove unnecessary blank line and space
  - replace uint(32|64) with standard uint(32|64)_t
