Ben Goz a22fc85495 drm/amdkfd: Add initial VI support for DQM
This patch starts to add support for the VI APU in the DQM module.

Because most (more than 90%) of the DQM code is shared among AMD's APUs, we
chose a design that performs most/all the code in the shared DQM file
(kfd_device_queue_manager.c). If there is H/W specific code to be executed,
than it is written in an asic-specific extension function for that H/W.

That asic-specific extension function is called from the shared function at the
appropriate time. This requires that for every asic-specific extension function
that is implemented in a specific ASIC, there will be an equivalent
implementation in ALL ASICs, even if those implementations are just stubs.

That way we achieve:

- Maintainability: by having one copy of most of the code, we only need to
  fix bugs at one locations

- Readability: very clear what is the shared code and what is done per ASIC

- Extensibility: very easy to add new H/W specific files/functions
