    drm/amdgpu: Switch baremetal to use KIQ for compute ring management.

    KIQ is the Kernel Interface Queue for managing the MEC.  Rather than
setting
    up rings via direct MMIO of ring registers, the rings are configured via
    special packets sent to the KIQ.  The allows the MEC to better manage
shared
    resources and certain power events.
