drm/amdgpu: add workarounds for VCN TMZ issue on CHIP_RAVEN
It is a hardware issue that VCN can't handle a GTT
backing stored TMZ buffer on CHIP_RAVEN series ASIC.
Move such a TMZ buffer to VRAM domain before command
submission as a workaround.
v2:
- Use patch_cs_in_place callback.
v3:
- Bail out early if unsecure IBs.
