[PATCH 3/8] lib/amdgpu: Add user mode queue support in ring context

[Sunil Khatri]

Add the meta data to support the user mode command
submission in the ring_context.

User mode command submission methods needs these
resources to be initialized and to create/destroy queues.

Also once we have the queue created the queue id is
used to submit the work load to the h/w.
