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.
