[PATCH v2 06/10] drm/amdgpu: Missing multi-XCC support in MES

[Amber Lin <Amber.Lin@amd.com>]

In a multi-XCC GPU, pass the master XCC's ID to amdgpu_mes_suspend,
amdgpu_mes_resume, and detect_and_reset_hung_queues so the command will be
sent to the matching master MES when the compute partition mode is not
SPX.
