drm/amdgpu: fix race between pstate and remote buffer map

2020-04-22T22:11:46Z

Vega20 arbitrates pstate at hive level and not device level. Last peer to remote buffer unmap could drop P-State while another process is still remote buffer mapped. With this fix, P-States still needs to be disabled for now as SMU bug was discovered on synchronous P2P transfers. This should be fixed in the next FW update.
