drm/amdgpu: Improve ualink state transitions

Browse source

Keep state transitions under lock. Validate the ppod/vpod config or both
based on the state passed by ASP. When a config update is received, if
the GPU is already active on a vpod, local vpod gpu integrity check is
skipped to keep minimal disruption. A gpu removed from the vpod will get
the new vpod id as 0. A GPU is not expected to transition directly from a
valid/nonzero vpod id to another valid vpod id. It needs to be removed
from the existing vpod first.
