drm/amdgpu/mes12: restore collateral gfx queues after pipe reset

Browse source

A pipe reset restarts the shared PFP/ME, but CP firmware dequeues only
the requested queue. Wait for its CP_VMID_RESET bit and HQD_ACTIVE to
clear, and return -ETIMEDOUT if recovery does not complete.

Preempt each collateral kernel queue and wait for its HQD to deactivate
before rebuilding its MQD/ring and remapping it. Leave the guilty kernel
queue to the outer reset helper.
