drm/amdgpu: add workarounds for VCN TMZ issue on CHIP_RAVEN

Browse source

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.
