This patch creates a new structure for asic specific operations, instead of using the existing structure of operations.
This is done to make the code flow more logic, readable and maintainable.
The change is done only to the device queue manager module at this point.

};
From what I currently know, this is only required for sdma queues,
because the vm info is in a register per queue. In compute queues, there are shared registers (sh_mem_*) so we don't need to init something per queue.
