driver (Mukul)
- Add new definition for soc21 device.
- Add new file for amdgpu-kfd interface for GFX11 family.
- Add new file for queue management, interrupt handling,
mqd management for GFX11 family in KFD driver.
- Related changes/updates for soc21 device in
KFD driver.
- Repurpose last 2 entries of SDMA MQD for driver use.
