drm/amdkfd: Add KFD support for soc21 v3

Add initial support for soc21 in KFD compute
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.

v2: Add an optional argument into update queue operation (Mukul)

v3: Switch to ip version check, replace kgd_dev with
    amdgpu_device (Hawking)
