A logical AND operation was used during mask and shift, instead of a
bitwise AND operation. This patch fixes this bug by changing the
operation to bitwise AND.

This patch adds support for the VI APU in the DQM module.
Most of the functionality of DQM is shared between CI and VI. Therefore,
only a handful of functions are required to be in the
H/W-specific part of DQM.

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.

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
